본 발명은 이동통신단말기의 성능 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring performance of a mobile communication terminal.

이동통신단말기를 개발하거나 수리하는 경우 각 기능이 정상적으로 동작되는 지 여부를 확인하기 위해 성능을 테스트한다. 성능 테스트 시 무선신호를 송수신하는 RF회로 부분에 대해서는, 송수신출력, 주파수 품질 등의 RF기능을 측정하여 불 량여부를 선별하고 있다.When developing or repairing a mobile communication terminal, performance is tested to confirm that each function is operating normally. In the part of the RF circuit that transmits and receives the radio signal during the performance test, the RF function such as the transmit / receive output and the frequency quality is measured to screen out the defects.

이에, 이동통신단말기는 RF OUT포트를 구비하여 RF회로에 대한 성능 측정 시, RF OUT포트에 측정장치의 단자를 연결하여 주파수 신호를 입력시키거나 입력된 주파수 신호를 출력시켜, 주파수, 출력 등을 비교 및 검토하며 측정하게 된다.Therefore, the mobile communication terminal is provided with an RF OUT port, when measuring the performance of the RF circuit, by connecting a terminal of the measuring device to the RF OUT port to input a frequency signal or output the input frequency signal, frequency, output, etc. Compare, review and measure.

그런데, 이동통신단말기의 제조회사나 모델에 따라 RF OUT포트의 위치가 상이할 수 있다. 예컨대, 한국의 규격에 따른 이동통신단말기의 경우 RF OUT포트가 배면(rear) 측에 위치한 반면, 일본의 규격에 따른 WCDMA 이동통신단말기(L600i, 등)의 경우 RF OUT포트가 본체 하단에 마련된 I/O소켓(receptacle)에 위치한다.However, the position of the RF OUT port may be different depending on the manufacturer or model of the mobile communication terminal. For example, in the case of a mobile communication terminal according to the Korean standard, the RF OUT port is located on the rear side, whereas in the case of a WCDMA mobile communication terminal (L600i, etc.) according to the Japanese standard, the RF OUT port is provided at the bottom of the main body. It is located in the / O socket (receptacle).

이에, RF OUT포트의 위치가 상이한 이동통신단말기의 경우 측정장치의 셋트를 RF OUT포트의 위치에 맞도록 다시 셋팅하는 것이 용이하지 아니하며, I/O소켓의 RF OUT포트에 검사장치를 연결하는 경우 테스트신호가 손실되어 테스트의 신뢰도가 저하되는 문제점이 있었다.Therefore, in the case of a mobile communication terminal having a different position of the RF OUT port, it is not easy to set the measuring device again to match the position of the RF OUT port, and to connect the inspection device to the RF OUT port of the I / O socket. There was a problem that the test signal is lost and the reliability of the test is lowered.

본 발명은 전술한 문제점을 해결하기 위해 안출 된 것으로서, 이동통신단말기를 제조하는 각 제조사 및 모델에 따라 RF OUT포트의 위치가 서로 달라지더라도 용이하게 성능 테스트를 수행할 수 있도록 하는 이동통신단말기의 성능 측정장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, the mobile communication terminal of the mobile communication terminal to facilitate the performance test even if the position of the RF OUT port is different according to each manufacturer and model of manufacturing the mobile communication terminal The purpose is to provide a performance measuring device.

전술한 목적을 달성하기 위한 본 발명에 따른 이동통신단말기의 성능 측정장치는, 이동통신단말기의 배면(rear) RF OUT포트와 접속되는 제1입출력 단자와; 이 동통신단말기의 I/O커넥터의 RF OUT포트와 접속되는 제2입출력 단자와; 성능 측정용 테스트신호가 입력되는 입력단자를 가지며; 외부로부터 입력되는 I/O커넥터 접속신호에 따라 스위칭 동작하여 상기 테스트신호를 상기 제1입출력 단자 및 제2입출력 단자 중 어느 한 측으로 출력하는 스위치부를 포함하는 것을 특징으로 한다.According to an aspect of the present invention, there is provided a performance measuring apparatus of a mobile communication terminal, comprising: a first input / output terminal connected to a rear RF OUT port of a mobile communication terminal; A second input / output terminal connected to the RF OUT port of the I / O connector of the copper communication terminal; An input terminal to which a test signal for performance measurement is input; And a switch unit configured to switch according to an I / O connector connection signal input from the outside to output the test signal to either one of the first input / output terminal and the second input / output terminal.

여기서, 이동통신단말기의 I/O커넥터 접속신호가 인가된 경우, 상기 제1입출력 단자가 접지되는 것이 가능하다.Here, when the I / O connector connection signal of the mobile communication terminal is applied, it is possible to ground the first input and output terminals.

이하에서는 첨부한 도면을 참조하여 본 발명의 바람직한 실시예에 따른 이동통신단말기의 성능 측정장치에 대해서 상세하게 설명한다.Hereinafter, an apparatus for measuring performance of a mobile communication terminal according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 이동통신단말기의 성능 측정장치의 제어블럭도로서, 테스트신호 생성부(1)에서 출력된 RF 성능 측정을 위한 테스트신호가 입력되는 입력단자와, 이동통신단말기의 배면(rear) RF OUT포트와 접속되는 제1입출력 단자인 Rear RF OUT단자(5)와, 이동통신단말기의 I/O커넥터(receptacle)의 RF OUT포트와 접속되는 제2입출력 단자인 Receptacle RF OUT단자(7)를 가지며, 외부로부터 입력되는 I/O커넥터 접속신호(AC/T)에 따라 스위칭 동작하여 테스트신호를 Rear RF OUT단자(5) 및 Receptacle RF OUT단자(7) 중 어느 한 측으로 출력하는 스위치(3)를 포함한다. 1 is a control block diagram of a performance measuring apparatus of a mobile communication terminal according to the present invention, an input terminal to which a test signal for measuring RF performance output from the test signal generator 1 is input, and a rear surface of the mobile communication terminal ( rear) Rear RF OUT terminal 5, which is a first input / output terminal connected to the RF OUT port, and Receptacle RF OUT terminal, which is a second input / output terminal connected to the RF OUT port of the I / O connector of the mobile communication terminal. 7) and a switch for switching the output signal to either of the rear RF OUT terminal 5 and the receptacle RF OUT terminal 7 by switching according to an I / O connector connection signal (AC / T) input from the outside. It includes (3).

RF OUT포트가 I/O커넥터에 마련된 이동통신단말기가 성능 측정장치에 접속되면 I/O커넥터 접속신호(AC/T)가 발생하여 스위치(3)로 입력되며, 이에, 스위치(3)는 테스트신호 생성부(1)에서 출력된 테스트신호를 Receptacle RF OUT단자(7)로 제 공하고 Receptacle RF OUT단자(7)로 입력되는 신호를 수신한다. When the mobile communication terminal provided with the RF OUT port is connected to the performance measuring device, an I / O connector connection signal (AC / T) is generated and input to the switch 3, whereby the switch 3 is tested. The test signal output from the signal generator 1 is provided to the receptacle RF OUT terminal 7 and receives a signal input to the Receptacle RF OUT terminal 7.

한편, I/O커넥터 접속신호(AC/T)가 발생하지 아니한 경우 스위치(3)는 테스트신호 생성부(1)에서 출력된 테스트신호를 Rear RF OUT단자(5)로 제공하고 Rear RF OUT단자(7)로 입력되는 신호를 수신한다. On the other hand, when the I / O connector connection signal (AC / T) does not occur, the switch 3 provides the test signal output from the test signal generator 1 to the Rear RF OUT terminal 5 and the Rear RF OUT terminal. Receive a signal input to (7).

이에 따라, 측정장치의 세팅을 재설정하거나 별도의 장비를 추가하지 아니하고도 RF OUT포트가 I/O커넥터에 마련된 이동통신단말기 및 배면(Rear)부에 RF OUT포트가 마련된 이동통신단말기의 성능 측정을 용이하게 할 수 있다.Accordingly, it is possible to measure the performance of the mobile communication terminal provided with the RF OUT port in the I / O connector and the mobile communication terminal provided with the RF OUT port in the rear part without resetting the setting of the measuring device or adding additional equipment. It can be done easily.

여기서, 스위치(3)는 스위치IC(예컨대, UPG2010B-E3)(30)를 적용할 수 있으며, 이러한 경우 회로는 도 2에 도시된 바와 같이 구성될 수 있다.Here, the switch 3 may apply a switch IC (eg, UPG2010B-E3) 30, in which case the circuit may be configured as shown in FIG. 2.

스위치부(3)로서 스위치IC UPG2010B-E3(30)를 적용하는 경우, 스위치IC UPG2010B-E3(10)의 입력핀(IN)에는 테스트신호 생성부(1)에서 생성된 테스트신호가 입력된다. VDD핀에는 2.85V의 레퍼런스 전압이 입력되며, I/O커넥터 접속신호(AC/T)는 VCONT핀으로 입력되는 한편 접지면으로 연결된다. When the switch IC UPG2010B-E3 30 is applied as the switch unit 3, the test signal generated by the test signal generator 1 is input to the input pin IN of the switch IC UPG2010B-E3 10. A reference voltage of 2.85V is input to the VDD pin, and the I / O connector connection signal (AC / T) is input to the VCONT pin and connected to the ground plane.

또한, 스위치IC UPG2010B-E3(30)는 Rear RF OUT단자(5)로 출력되는 OUT2핀과 Rear RF OUT단자(7)로 출력되는 OUT1핀을 갖는다.In addition, the switch IC UPG2010B-E3 30 has an OUT2 pin output to the rear RF OUT terminal 5 and an OUT1 pin output to the Rear RF OUT terminal 7.

이에, 배면(rear)에 RF OUT포트를 갖는 이동통신단말기가 측정장치에 접속된 경우 VDD핀으로 레퍼런스 전압이 인가되고 입력핀(IN)으로는 테스트신호가 인가되어 출력핀인 OUT2가 턴온된다. 이에, 스위치 SW101을 통해 Rear RF OUT단자(5)로 테스트신호가 출력된다.Therefore, when a mobile communication terminal having an RF OUT port at the rear is connected to a measurement device, a reference voltage is applied to the VDD pin and a test signal is applied to the input pin IN, so that the output pin OUT2 is turned on. Thus, a test signal is output to the rear RF OUT terminal 5 through the switch SW101.

한편, 이동통신단말기의 I/O커넥터(Receptacle)가 측정장치에 접속된 경우 I/O커넥터 접속신호(AC/T)가 입력되어 접지(GND)로 연결된다. 이에, VDD핀으로 입력되는 레퍼런스 전압 또한 접지되어 스위치IC(30)는 스위칭 동작하게 된다. 이에 따라, 출력핀인 OUT1이 턴온되어 테스트신호가 Rear RF OUT단자(5)로 출력된다.Meanwhile, when the I / O connector of the mobile communication terminal is connected to the measuring device, the I / O connector connection signal AC / T is input and connected to the ground GND. Accordingly, the reference voltage input to the VDD pin is also grounded, so that the switch IC 30 switches. Accordingly, the output pin OUT1 is turned on and the test signal is output to the rear RF OUT terminal 5.

The I / O connector connection signal (AC / T) is output from the A pin 64.

A핀(64)에서 출력된 I/O커넥터 접속신호(AC/T)는 스위치IC(30)으로 인가되어 VDD핀으로 입력되는 레퍼런스 전압(2.8V)를 접지시킨다. 이에, 스위치IC(30)의 출력핀 OUT1이 턴온되어 입력핀 IN으로 인가된 테스트신호가 OUT1 출력핀을 통해 출력된다. OUT1출력핀은 I/O커넥터(receptacle)(60)의 RF OUT단자로 할당된 INNER핀(62)과 접속되어, 테스트신호를 INNER핀(62)을 통해 검사대상 이동통신단말기(50)에 제공한다.  The I / O connector connection signal AC / T output from the A pin 64 is applied to the switch IC 30 to ground the reference voltage (2.8V) input to the VDD pin. Accordingly, the output pin OUT1 of the switch IC 30 is turned on and the test signal applied to the input pin IN is output through the OUT1 output pin. The OUT1 output pin is connected to the INNER pin 62 assigned to the RF OUT terminal of the I / O connector 60 to provide a test signal to the mobile communication terminal 50 under test through the INNER pin 62. do.

It is output to the terminal 7 or the rear RF OUT terminal 5.

이상, 본 발명에 따른 실시예는 상술한 것에 한정되지 아니하고, 본 발명과 관련하여 통상의 지식을 가진자에게 자명한 범위 내에서 다양하게 변형하여 실시할 수 있다.As described above, the embodiment according to the present invention is not limited to the above, and various modifications can be made within the scope apparent to those skilled in the art in connection with the present invention.

이상에서 설명한 바와 같은 본 발명의 이동통신단말기의 성능 측정장치는, 스위치IC를 이용하여 테스트신호를 Rear RF OUT포트 및 Receptacle RF OUT포트 중 어느 한 측으로 출력하고, 해당 포트를 통해 신호를 송수신할 수 있도록 하고 있다.As described above, the performance measuring apparatus of the mobile communication terminal of the present invention outputs a test signal to one of a rear RF OUT port and a receptacle RF OUT port by using a switch IC, and transmits and receives a signal through the corresponding port. To make it work.

이에 따라, 이동통신단말기를 제조하는 각 제조사 및 모델에 따라 RF OUT포트의 위치가 서로 달라지더라도 용이하게 성능 테스트를 수행할 수 있다.Accordingly, even if the position of the RF OUT port is different according to each manufacturer and model of manufacturing the mobile communication terminal, the performance test can be easily performed.
