Description

本発明は、通信機器の筺体内に収容された複数の無線デバイスの検査技術に関する。 The present invention relates to an inspection technique for a plurality of wireless devices accommodated in a housing of a communication device.

携帯電話機などの通信機器は、複数の無線デバイスを筺体内に備え、無線デバイスの検査が行われる。
無線デバイスの検査手法として、例えば、無線デバイスと検査器との間で無線通信にて検査信号を送受信することによって、無線デバイスの検査を行う。この手法は、検査信号の送受信が無線通信にて行われるため、周囲の環境の影響を受けやすく、無線デバイスを定量的に検査することが難しい。 A communication device such as a mobile phone includes a plurality of wireless devices in a casing, and the wireless devices are inspected.
As a wireless device inspection method, for example, a wireless device is inspected by transmitting and receiving an inspection signal by wireless communication between the wireless device and the inspector. In this method, since the inspection signal is transmitted and received by wireless communication, it is easily affected by the surrounding environment, and it is difficult to quantitatively inspect the wireless device.

検査信号の送受信を無線通信ではなく、有線通信にて行う検査手法も各種提案されている。第１の検査手法として、無線デバイスの接続先をアンテナ素子と筺体に設けられたコネクタとの間で切り替えるスイッチを設ける。検査時、スイッチによって無線デバイスの接続先をコネクタにし、検査器をケーブルでコネクタに接続する。そして、検査器と無線デバイスとの間で有線通信にて検査信号を送受信することによって、無線デバイスの検査を行う。 Various inspection methods have been proposed in which inspection signals are transmitted and received by wired communication instead of wireless communication. As a first inspection method, a switch for switching a connection destination of the wireless device between the antenna element and the connector provided in the housing is provided. At the time of inspection, the connection destination of the wireless device is a connector by a switch, and the inspection device is connected to the connector by a cable. And a wireless device is test | inspected by transmitting / receiving an inspection signal by wired communication between an inspection device and a wireless device.

また、第２の検査手法として、検査対象の無線デバイスとアンテナとを接続する信号導通線上にＲＦ（Radio Frequency）コネクタを設け、ＲＦコネクタに無線デバイスの高周波特性検査用の検査器を接続する。検査器からＲＦコネクタ経由で無線デバイスの検査を行う（例えば、特許文献１参照。）。 As a second inspection method, an RF (Radio Frequency) connector is provided on a signal conduction line that connects a wireless device to be inspected and an antenna, and an inspection device for high-frequency characteristic inspection of the wireless device is connected to the RF connector. The wireless device is inspected from the inspection device via the RF connector (see, for example, Patent Document 1).

ところで、通信機器には、複数の無線デバイスが筺体内に収容されており、複数の無線デバイスの検査が行われる。筺体内に収容された複数の無線デバイスの検査に上記の第１の検査手法を単に適用すると、検査対象の無線デバイスの数だけコネクタが必要となり、コスト上昇につながる。
また、上記の第２の検査手法を単に適用すると、検査対象の無線デバイスの数だけＲＦコネクタが必要となり、検査器をＲＦコネクタに接続するためのケーブルを筺体内に通すための開口をＲＦコネクタの数だけ筺体に設ける必要がある。このため、通信機器のコスト上昇につながるとともに、外観の見栄えが悪くなる。 By the way, a plurality of wireless devices are accommodated in the housing in the communication device, and the plurality of wireless devices are inspected. If the first inspection method described above is simply applied to the inspection of a plurality of wireless devices accommodated in the housing, the number of connectors required for the number of wireless devices to be inspected increases the cost.

なお、どのようなパラメータ（挿入損失、結合度、アイソレーション、方向性など）を持つ方向性結合器を方向性結合器１６，１７，１８，１９に用いるかは、次のことを考慮することによって行う。方向性結合器１６，１７，１８，１９によってＧＰＳデバイス１２、ＢＴデバイス１３、ＤＴＶデバイス１４の性能劣化が起こらないよう、挿入損失を低くする。また、送信機能があるＢＴデバイス１３などを接続する場合は送信波によって他の無線デバイスの性能が劣化しないよう、結合度、アイソレーションを決める。 It should be noted that what kind of parameters (insertion loss, degree of coupling, isolation, directionality, etc.) the directional coupler is used for the directional couplers 16, 17, 18, 19 should be considered as follows. Do by. The insertion loss is lowered so that the directional couplers 16, 17, 18, and 19 do not cause performance degradation of the GPS device 12, the BT device 13, and the DTV device 14. Further, when connecting a BT device 13 having a transmission function or the like, the degree of coupling and isolation are determined so that the performance of other wireless devices is not deteriorated by the transmission wave.

＜ＣＤＭＡ送受信デバイスの検査時の検査信号の伝送経路＞
ＣＤＭＡ送受信デバイス１１の検査時には、スイッチ１５では上述したように端子１５ａと端子１５ｃとが接続される。
コネクタ１０に接続された検査器Ｄから送信されたＣＤＭＡ送受信デバイス１１の検査信号は、コネクタ１０、方向性結合器１６のポートＰＡ１、ポートＰＡ２、スイッチ１５を経由してＣＤＭＡ送受信デバイス１１へ伝送され、ＣＤＭＡ送受信デバイス１１は検査信号に応じた動作を行う。 <Transmission path of inspection signal during inspection of CDMA transceiver device>
When the CDMA transceiver device 11 is inspected, the switch 15 connects the terminal 15a and the terminal 15c as described above.
The inspection signal of the CDMA transmission / reception device 11 transmitted from the inspection device D connected to the connector 10 is transmitted to the CDMA transmission / reception device 11 via the connector 10, the port PA1, the port PA2, and the switch 15 of the directional coupler 16. The CDMA transmission / reception device 11 performs an operation according to the inspection signal.

また、ＣＤＭＡ送受信デバイス１１から送信された自デバイスの検査信号は、スイッチ１５、方向性結合器１６のポートＰＡ２、ポートＰＡ１、コネクタ１０を経由して検査器Ｄへ伝送され、検査器Ｄは検査信号に応じた動作を行う。
ここで、図２及び後述する図３に示されるように、ＣＤＭＡ送受信デバイス１１と、アンテナ素子１１ａ及びコネクタ１０を経由した検査器Ｄとの接続を切り替えるためにスイッチ１５を用いている理由は次の理由からである。すなわち、ＣＤＭＡ送受信デバイス１１は、送信電力の制御の際に他の無線デバイス（例えば、ＢＴデバイス１３）に比べてより正確な送信電力制御を必要とする。そのため、ＣＤＭＡ送受信デバイス１１の場合は、スイッチ１５により、ＣＤＭＡ送受信デバイス１１と、アンテナ素子１１ａ及びコネクタ１０を経由した検査器Ｄとの接続の切り替えを行い、検査の際にＣＤＭＡ送受信デバイス１１から検査器Ｄへ出力を行うことにより、例えば、ＢＴデバイス１３のように、方向性結合器１８などを用いる場合に比べて、方向性結合器１８などの通過特性のずれなどを除外してより正確な検査を行うことを可能とする。 The inspection signal of the device transmitted from the CDMA transmitting / receiving device 11 is transmitted to the inspection device D via the switch 15, the port PA2, the port PA1, and the connector 10 of the directional coupler 16, and the inspection device D performs the inspection. Operates according to the signal.
Here, as shown in FIG. 2 and FIG. 3 described later, the reason why the switch 15 is used to switch the connection between the CDMA transmission / reception device 11 and the inspection device D via the antenna element 11a and the connector 10 is as follows. Because of the reason. That is, the CDMA transmission / reception device 11 requires more accurate transmission power control than other wireless devices (for example, the BT device 13) when controlling transmission power. Therefore, in the case of the CDMA transmission / reception device 11, the switch 15 switches the connection between the CDMA transmission / reception device 11 and the inspection device D via the antenna element 11a and the connector 10, and the inspection is performed from the CDMA transmission / reception device 11 at the time of inspection. By performing output to the coupler D, for example, compared with the case where the directional coupler 18 or the like is used as in the BT device 13, it is more accurate by excluding the deviation in pass characteristics of the directional coupler 18 or the like. It is possible to perform an inspection.

これによって、ＣＤＭＡ送受信デバイス１１の受信特性や送信特性の検査が可能になる。
＜ＧＰＳデバイスの検査時の検査信号の伝送経路＞

<Transmission path of inspection signal during inspection of BT device>
The inspection signals of the BT device 13 transmitted from the inspection device D connected to the connector 10 are the connector 10, the port PA1, the port PA3 of the directional coupler 16, the port PB4, the port PB3 of the directional coupler 17, and the directionality. The data is transmitted to the BT device 13 via the port PC4 and the port PC2 of the coupler 18. The BT device 13 performs an operation according to the inspection signal.

The second embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, the mechanism for coupling the connector 10 with the GPS device 12, the BT device 13, and the DTV device 14 is changed from the first embodiment.

＜携帯電話機の内部構成＞
本実施の形態の携帯電話機の内部構成について図３を参照しつつ説明する。図３は本実施の形態の携帯電話機の下部筺体４内の回路図である。なお、第１の実施の形態の構成要素と実質的に同じ構成要素には同じ符号を付し、その説明が適用できるためここでは省略する。 <Internal configuration of mobile phone>
The internal configuration of the mobile phone according to the present embodiment will be described with reference to FIG. FIG. 3 is a circuit diagram in the lower housing 4 of the mobile phone according to the present embodiment. Note that components that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted here because they can be applied.

第１の実施の形態と異なり、スイッチ１５の端子１５ｃとコネクタ１０とは直接接続され、ＧＰＳデバイス１２とアンテナ素子１２ａとは直接接続され、ＢＴデバイス１３とアンテナ素子１３ａとは直接接続され、ＤＴＶデバイス１４とアンテナ素子１４ａとは直接接続されている。
携帯電話機１は、下部筺体４内に、一端がアンテナ素子１２ａからＧＰＳデバイス１２にかけての伝送線路ＬＢ２に接続され、他端がコネクタ１０からスイッチ１５の端子１５ｃにかけての伝送線路ＬＡ２に接続された結合コンデンサ３１を備える。また、携帯電話機１は、下部筺体４内に、一端がアンテナ素子１３ａからＢＴデバイス１３にかけての伝送線路ＬＣ２に接続され、他端がコネクタ１０からスイッチ１５の端子１５ｃにかけての伝送線路ＬＡ２に接続された結合コンデンサ３２を備える。更に、携帯電話機１は、下部筺体４内に、一端がアンテナ素子１４ａからＤＴＶデバイス１４にかけての伝送線路ＬＤ２に接続され、他端がコネクタ１０からスイッチ１５の端子１５ｃにかけての伝送線路ＬＡ２に接続された結合コンデンサ３３を備える。 Unlike the first embodiment, the terminal 15c of the switch 15 and the connector 10 are directly connected, the GPS device 12 and the antenna element 12a are directly connected, the BT device 13 and the antenna element 13a are directly connected, and the DTV The device 14 and the antenna element 14a are directly connected.
The mobile phone 1 is coupled in the lower housing 4 with one end connected to the transmission line LB2 from the antenna element 12a to the GPS device 12 and the other end connected to the transmission line LA2 from the connector 10 to the terminal 15c of the switch 15. A capacitor 31 is provided. Further, the mobile phone 1 has one end connected to the transmission line LC2 from the antenna element 13a to the BT device 13 and the other end connected to the transmission line LA2 from the connector 10 to the terminal 15c of the switch 15 in the lower casing 4. The coupling capacitor 32 is provided. Further, the mobile phone 1 has one end connected to the transmission line LD2 from the antenna element 14a to the DTV device 14 in the lower casing 4, and the other end connected to the transmission line LA2 from the connector 10 to the terminal 15c of the switch 15. The coupling capacitor 33 is provided.

なお、どのような容量を持つコンデンサを結合コンデンサ３１，３２，３３に用いるかは、次のことを考慮することによって行う。ＣＤＭＡ送受信デバイス１１の検査が正確に行えることと、実用の際に、ＧＰＳデバイス１２、ＢＴデバイス１３、ＤＴＶデバイス１４の結合によって性能劣化が起こらないよう、結合度を低くする必要がある。コンデンサ３１、３２、３３の容量値は、夫々、（１）接続されるＧＰＳデバイス１２、ＢＴデバイス１３、ＤＴＶデバイス１４で通信を行う周波数が、ＣＤＭＡ送受信デバイス１１で通信を行う周波数のうち最も高い周波数より高い場合、図３の例ではＢＴデバイス１３が該当し、ＢＴデバイス１３の周波数における通過特性が−２０ｄＢ程度になるようにコンデンサ３２の容量値を決定し、（２）接続されるＧＰＳデバイス１２、ＢＴデバイス１３、ＤＴＶデバイス１４で通信を行う周波数が、ＣＤＭＡ送受信デバイス１１で通信を行う周波数のうち最も高い周波数より低い場合、図３の例ではＧＰＳデバイス１２、ＤＴＶデバイス１４が該当し、ＣＤＭＡの最も高い周波数における通過特性が−２０ｄＢ程度になるように、コンデンサ３１，３３の容量値を設定する。 In addition, what kind of capacitor | condenser is used for the coupling capacitors 31, 32, and 33 is performed by considering the following. It is necessary to reduce the degree of coupling so that the inspection of the CDMA transmission / reception device 11 can be performed accurately and in practical use, performance degradation does not occur due to the coupling of the GPS device 12, the BT device 13, and the DTV device 14. The capacitance values of the capacitors 31, 32, and 33 are (1) the frequency at which communication is performed with the connected GPS device 12, BT device 13, and DTV device 14 among the frequencies at which communication is performed with the CDMA transmission / reception device 11. When the frequency is higher than the frequency, the example of FIG. 3 corresponds to the BT device 13, and the capacitance value of the capacitor 32 is determined so that the pass characteristic at the frequency of the BT device 13 is about −20 dB, and (2) the connected GPS device. 12, when the frequency at which the BT device 13 and the DTV device 14 communicate is lower than the highest frequency among the frequencies at which the CDMA transmission / reception device 11 communicates, the GPS device 12 and the DTV device 14 correspond to the example in FIG. Capacitor so that the pass characteristic at the highest frequency of CDMA is about -20 dB. To set the capacitance value of 1,33.

このように、コンデンサ３２の容量値をＢＴデバイス１３の周波数における通過特性が−２０ｄＢ程度となるようにしているのは、コンデンサによる接続は周波数が高いほど低い容量で結合度が高くなるために、高い周波数であるＢＴデバイス１３の周波数に着目し、ＢＴデバイス１３の出力やＢＴデバイス１３への入力がコンデンサ３２との結合により、アンテナ素子１３ａ及びＢＴデバイス１３以外にできるだけ漏れないように、コンデンサ３２の容量値を設定している。なお、上記−２０ｄＢという値は適宜変更することができ、本発明をこの−２０ｄＢの値に限定するものではない。 In this way, the capacitance value of the capacitor 32 is set so that the pass characteristic at the frequency of the BT device 13 is about −20 dB because the connection by the capacitor has a lower capacity and a higher coupling degree as the frequency is higher. Focusing on the frequency of the BT device 13 which is a high frequency, the capacitor 32 is arranged so that the output of the BT device 13 and the input to the BT device 13 do not leak as much as possible to the antenna element 13 a and the BT device 13 by coupling with the capacitor 32. The capacity value is set. The value of −20 dB can be changed as appropriate, and the present invention is not limited to this value of −20 dB.

また、コンデンサ３１，３３の容量値をＣＤＭＡの最も高い周波数の通過特性が−２０ｄＢ程度となるようにしているのは、ＣＤＭＡ送受信デバイス１１を検査する際に、ＣＤＭＡ送受信デバイス１１の出力及びＣＤＭＡ送受信デバイス１１への入力が、コンデンサ３１，３３などの結合により検査器Ｄ及びＣＤＭＡ送受信デバイス１１以外へと漏れるのをできるだけ防止するためである。なお、上記−２０ｄＢという値は適宜変更することができ、本発明をこの−２０ｄＢの値に限定するものではない。 The capacitance values of the capacitors 31 and 33 are set so that the pass characteristic of the highest frequency of CDMA is about −20 dB when the output of the CDMA transmission / reception device 11 and the CDMA transmission / reception when the CDMA transmission / reception device 11 is inspected. This is to prevent the input to the device 11 from leaking to other than the tester D and the CDMA transmission / reception device 11 due to the coupling of the capacitors 31 and 33 as much as possible. The value of −20 dB can be changed as appropriate, and the present invention is not limited to this value of −20 dB.

このように、コンデンサによる接続は周波数が高いほど低い容量で結合度が高くなるために、高い周波数に着目しその結合を低く抑えている。
ＣＤＭＡ送受信デバイス１１の検査信号は、ＣＤＭＡ送受信デバイス１１とコネクタ１０との間をスイッチ１５を介して伝送する。ＧＰＳデバイス１２の検査信号は、ＧＰＳデバイス１２とコネクタ１０との間を結合コンデンサ３１を介して伝送する。ＢＴデバイス１３の検査信号は、ＢＴデバイス１３とコネクタ１０との間を結合コンデンサ３２を介して伝送する。ＤＴＶデバイス１４の検査信号は、ＤＴＶデバイス１４とコネクタ１０との間を結合コンデンサ３３を介して伝送する。 As described above, since the connection with the capacitor has a lower capacity and a higher degree of coupling as the frequency is higher, the coupling is kept low by focusing on the higher frequency.
The inspection signal of the CDMA transmission / reception device 11 is transmitted between the CDMA transmission / reception device 11 and the connector 10 via the switch 15. The inspection signal of the GPS device 12 is transmitted between the GPS device 12 and the connector 10 via the coupling capacitor 31. The inspection signal of the BT device 13 is transmitted between the BT device 13 and the connector 10 via the coupling capacitor 32. The inspection signal of the DTV device 14 is transmitted between the DTV device 14 and the connector 10 via the coupling capacitor 33.

上述した実施の形態によれば、コネクタ１０が各デバイス１１〜１４で供用されているため、各デバイス１１〜１４の検査を可能としつつ、コネクタの数を抑えることができ、コスト上昇を抑えることができる。
また、結合コンデンサ３１〜３３を利用することによって、コネクタ１０と各デバイス１１〜１４との間の検査信号の伝送経路を簡易な構成にできる。 According to the above-described embodiment, since the connector 10 is used by the devices 11 to 14, the number of connectors can be suppressed while the devices 11 to 14 can be inspected, and an increase in cost can be suppressed. Can do.
Further, by using the coupling capacitors 31 to 33, the transmission path of the inspection signal between the connector 10 and each of the devices 11 to 14 can be simplified.

更に、コネクタ１０とＣＤＭＡ送受信デバイス１１間でＣＤＭＡ送受信デバイス１１の検査信号のロスは小さく、アンテナ素子１２ａ〜１４ａとＣＤＭＡ送受信デバイス１１間でアンテナ素子１２ａ〜１４ａによる受信信号のロスは大きいため、ＣＤＭＡ送受信デバイス１１の検査を高い精度で行うことができる。
上記の第１及び第２の夫々の実施の形態の通信機器によれば、コネクタが複数の無線デバイスで供用されるため、コネクタの削減が図られ、コストの上昇を抑えることが可能になるとともに、複数の開口を設けることによる外観の見栄えの悪さを回避できる。 Furthermore, the inspection signal loss of the CDMA transmission / reception device 11 is small between the connector 10 and the CDMA transmission / reception device 11, and the reception signal loss due to the antenna elements 12a-14a is large between the antenna elements 12a-14a and the CDMA transmission / reception device 11. Inspection of the transmission / reception device 11 can be performed with high accuracy.
According to the communication devices of the first and second embodiments described above, since the connector is used by a plurality of wireless devices, it is possible to reduce the number of connectors and suppress an increase in cost. In addition, it is possible to avoid poor appearance of the appearance by providing a plurality of openings.
