Description

増幅装置Amplifier
　本発明は、増幅装置に関し、特に複数系統の高周波増幅器を備えた増幅装置に関する。 The present invention relates to an amplifying device, and more particularly to an amplifying device including a plurality of high-frequency amplifiers.
　無線通信装置では、送信装置の出力段にアイソレータ或いはサーキュレータを具備することが行なわれている。アイソレータ或いはサーキュレータは、入力端子、出力端子及び終端用端子を備えている。入力端子は送信装置に接続され、出力端子はアンテナなど送信装置の外部機器に接続され、終端用端子には減衰器が接続される。送信装置はアイソレータ或いはサーキュレータを経由してアンテナから信号を送信する。 In a wireless communication device, an isolator or a circulator is provided at the output stage of a transmission device. The isolator or circulator includes an input terminal, an output terminal, and a termination terminal. The input terminal is connected to the transmitter, the output terminal is connected to an external device of the transmitter such as an antenna, and the attenuator is connected to the terminal for termination. The transmission device transmits a signal from the antenna via an isolator or a circulator.
　送信装置の出力端に接続される外部構成との間での高周波的な不整合により、出力端から増幅器に反射し戻ってくる信号は、アイソレータ或いはサーキュレータの出力端子から終端用端子を経て減衰器へ送られて、減衰する。出力端から増幅器に反射し戻ってくる信号は、送信装置の出力段にアイソレータ或いはサーキュレータを配置して、その終端用端子に高周波減衰器を配置して対処することが一般的である。特許文献１には、このような出力段にアイソレータ或いはサーキュレータを具備した送信装置が記載されている。 The signal reflected back from the output end to the amplifier due to a high frequency mismatch with the external configuration connected to the output end of the transmitter is attenuated from the output terminal of the isolator or circulator via the termination terminal. It is sent to and attenuates. In general, a signal reflected and returned from the output terminal to the amplifier is dealt with by arranging an isolator or a circulator at the output stage of the transmission apparatus and arranging a high-frequency attenuator at the terminal for termination. Japanese Patent Application Laid-Open No. 2004-228561 describes a transmission apparatus including an isolator or a circulator in such an output stage.

Further, the outputs of amplifiers 12 1 , 12 2 ,..., 12 2n−1 , 12 2n pass through output stage circulators 13 1 , 13 2 ,..., 13 2n−1 , 13 2n, and then output terminals OUT 1 , OUT 2 ,..., OUT 2n−1 , OUT 2n . For example, when an antenna is connected to the output terminal, output signals from the output terminals OUT 1 , OUT 2 ,..., OUT 2n−1 , OUT 2n are transmitted from the antenna, respectively.
　出力端子ＯＵＴ１、ＯＵＴ２、…、ＯＵＴ２ｎ－１、ＯＵＴ２ｎに接続される外部構成と高周波増幅器間に高周波的な不整合がある場合、高周波信号の一部が出力端子で反射され出力段サーキュレータ１３１、１３２、…、１３２ｎ－１、１３２ｎに戻ってくる。この戻ってきた信号は、サーキュレータ１３１、１３２、…、１３２ｎ－１、１３２ｎを通った後、減衰器１４１、…、１４２ｎ－１に入力され減衰する。 When there is a high frequency mismatch between the high frequency amplifier and the external configuration connected to the output terminals OUT 1 , OUT 2 ,..., OUT 2n−1 , OUT 2n , a part of the high frequency signal is reflected at the output terminal and the output stage Return to the circulators 13 1 , 13 2 ,..., 13 2n−1 , 13 2n . This returned signal passes through the circulators 13 1 , 13 2 ,..., 13 2n−1 , 13 2n and is then input to the attenuators 14 1 ,.
　この一連の動作は、図１の複数の高周波増幅器にて独立に実現しうる。例えば、図１において１番目の高周波増幅器１１１において増幅された信号の一部が出力端子で反射されて１番目の出力段サーキュレータ１３１を通じて１番目及び２番目の出力段サーキュレータに接続された１番目の減衰器１４１で減衰されることを、第１事象とする。さらに、２番目の高周波増幅器１１２において増幅された信号の一部が出力端子で反射されて２番目の出力段サーキュレータ１３２を通じて１番目及び２番目の出力段サーキュレータに接続された減衰器１４１で減衰されることを、第２事象とする。この第１事象と第２事象とは同時に起こっても良いし、別々に起こっても良い。 This series of operations can be realized independently by a plurality of high-frequency amplifiers in FIG. For example, connected to the first of the first through the first output stage circulator 13 1 part of the amplified signal is reflected at the output terminal in the high-frequency amplifier 11 1 and the second output stage circulator 1 1 Attenuation by the first attenuator 141 is a first event. Further, the second high-frequency amplifier 11 portion of the amplified signal in 2 is reflected at the output terminal the second output stage circulator 13 2 through the first and second connected attenuator output stage circulator 14 1 The second event is to be attenuated by. The first event and the second event may occur at the same time or may occur separately.
　１番目の高周波増幅器１１１で増幅される高周波信号と２番目の高周波増幅器１１２で増幅される高周波信号の間に何らかの相関があっても良いし、無相関であっても良い。減衰器１４１、…、１４２ｎ－１の減衰量としては１０ｄＢ以上あれば、高周波増幅器出力端から見込んだリターンロス特性として十分な特性が得られる。さらに、減衰器を共用している高周波増幅器間での高周波的分離が特別に必要な場合には、減衰器の減衰量を大きく、例えば３０ｄＢと、すれば良い。 It may be there is any correlation between the high frequency signal amplified by the first high-frequency amplifier 11 1 and the second high-frequency signal amplified by the RF amplifier 11 2 may be uncorrelated. If the attenuation of the attenuators 14 1 ,..., 14 2n−1 is 10 dB or more, sufficient characteristics can be obtained as the return loss characteristics expected from the output terminal of the high frequency amplifier. Further, when high frequency separation is particularly required between the high frequency amplifiers sharing the attenuator, the attenuation amount of the attenuator may be increased, for example, 30 dB.
　本実施形態による増幅装置によれば、出力段にサーキュレータ１３を具備し、その終端用端子に減衰器１４が配置されると共に、減衰器１４を複数の高周波増幅器１１で共用している。これにより、高周波増幅器１１を複数有し、複数の送信系統を備えた送信機に用いられる場合であっても、部品の点数の増大を抑制し、装置の小型化を図ることができる。特に隣接する高周波増幅器１１間で減衰器１４を共用しているので、高周波増幅器１１を複数有する増幅装置の寸法をより一層小さくすることができる。 According to the amplifying apparatus according to the present embodiment, the circulator 13 is provided in the output stage, the attenuator 14 is disposed at the terminal for termination, and the attenuator 14 is shared by the plurality of high-frequency amplifiers 11. Thereby, even if it is a case where it uses for the transmitter which has two or more high frequency amplifiers 11 and was provided with the some transmission system, the increase in the number of parts can be suppressed and size reduction of an apparatus can be achieved. In particular, since the attenuator 14 is shared between the adjacent high-frequency amplifiers 11, the size of the amplifying apparatus having a plurality of high-frequency amplifiers 11 can be further reduced.

A plurality of high-frequency amplifiers 41 are shared. Thereby, even if it is a case where it has a plurality of high frequency amplifiers 41 and is used for a transmitter provided with a plurality of transmission systems, increase in the number of parts can be controlled and size reduction of an apparatus can be attained. In particular, since the attenuator 49 is shared between the adjacent high frequency amplifiers 41, the size of the amplifying device having a plurality of high frequency amplifiers 41 can be further reduced.
　さらに、本実施形態では第３実施形態と同様に、隣接する高周波増幅器４１間で９０度ハイブリッド分配器４２２ｎ－１と９０度ハイブリッド分配器４２２ｎとに接続される減衰器を共用している。これにより、分配器を有する高周波増幅器において、送信機の寸法をより一層小さくすることができる。 Further, in the present embodiment, as in the third embodiment, the attenuators connected to the 90-degree hybrid distributor 42 2n-1 and the 90-degree hybrid distributor 42 2n are shared between the adjacent high-frequency amplifiers 41. . Thereby, in the high frequency amplifier having a distributor, the size of the transmitter can be further reduced.

Further, as shown in FIG. 4, the carrier amplifier 45 2n is arranged closer to the side closer to the other amplifier sharing the attenuator than the peak amplifier 44 2n . In other words, as the carrier amplifier 45 2n-1 and the carrier amplifier 45 2n are close, are arranged and the carrier amplifier 45 2n-1 and the carrier amplifier 45 2n in each amplifier. Thereby, component arrangement | positioning at the time of sharing an attenuator can be made easy.
