본 발명은 이동통신 단말기에 관한 것이며, 상세하게는 이동통신 단말기의 송신부에 주파수 대역을 송수신 대역으로 각각 분리하는 듀플렉스와 이 분리 신호를 증폭하는 전력 증폭기 모듈이 일체형으로 형성된 이동통신 단말기의 송신부 모듈에 관한 것이다.The present invention relates to a mobile communication terminal, and more particularly, to a transmitter module of a mobile communication terminal in which a duplex for separating a frequency band into transmission and reception bands and a power amplifier module for amplifying the separated signal are integrally formed in a transmission unit of a mobile communication terminal. It is about.

현재 이동통신 단말기는 그 수요가 급속도로 증가되어 개인 휴대용 통신수단 이상으로 이미 생활의 필수품이 되었다. 이제는 단순히 음성 송수신을 위한 통신수단의 기능만으로는 소비자의 욕구를 충족시키지 못하므로 다양하고 새로운 기능과 서비스가 부가된 이동통신 단말기가 출시되고 있다.At present, the demand for mobile communication terminals has increased rapidly, and has become a necessity of life beyond personal portable communication means. Now, since only the function of the communication means for transmitting and receiving voice does not satisfy the needs of consumers, various new functions and services have been introduced.

이러한 이동통신 단말기의 일반적인 구성을 보면 도 1과 같다.A general configuration of such a mobile communication terminal is shown in FIG. 1.

도 1은 종래 이동통신 단말기에의 일반적인 구성을 나타낸 구성도이다.1 is a block diagram showing a general configuration of a conventional mobile communication terminal.

도시된 바와 같이, 이동통신 단말기는 송수신부(101), 명령입력부(102), 음성입력부(103), 메모리부(104), 제어부(105), 음성출력부(106), 표시부(107)를 포함하여 이루어 진다.As shown, the mobile communication terminal includes a transceiver 101, a command input unit 102, a voice input unit 103, a memory unit 104, a control unit 105, a voice output unit 106, a display unit 107. It is made to include.

여기서, 송수신부(101)는 안테나를 통하여 외부로 음성과 영상 및 데이터 신호를 송, 수신한다.Here, the transceiver 101 transmits and receives audio, video, and data signals to the outside through an antenna.

명령 입력부(102)는 키패드등의 다양한 키들로 구비되고, 음성, 영상 또는 데이터 신호의 송, 수신 및 영상 촬영을 위한 제어 명령을 입력한다. The command input unit 102 is provided with various keys such as a keypad and inputs a control command for transmitting, receiving, and capturing an image of a voice, an image, or a data signal.

음성 입력부(103)는 마이크등으로 구비되고, 이동통신 단말기에서 통화 시 음성이 입력된다.The voice input unit 103 is provided with a microphone or the like, and voice is input during a call in the mobile communication terminal.

메모리부(104)는 이동통신 단말기에서 실행되는 컨텐츠나 전화번호, 이동통신 단말기의 고유정보등의 데이터가 저장되어 있다.The memory unit 104 stores data executed in the mobile communication terminal, such as contents, telephone numbers, and unique information of the mobile communication terminal.

제어부(105)는 음성, 영상 또는 데이터 신호의 송, 수신등을 제어한다.The controller 105 controls transmission and reception of audio, video or data signals.

음성 출력부(106)는 스피커등의 음성 출력 수단으로 이루어져 음성 신호를 사용자가 청취 가능하도록 출력한다.The voice output unit 106 includes voice output means such as a speaker and outputs a voice signal so that a user can listen.

표시부(107)는 LCD(Liquid Crystal Display) 등의 평판 표시 장치로 구비되고, 문자 또는 영상 등을 화면상에 표시한다.The display unit 107 is provided with a flat panel display device such as an LCD (Liquid Crystal Display), and displays characters or images on the screen.

위와 같이 이루어진 이동통신 단말기에서 데이터를 송신하는 과정을 살펴보면, 명령입력부(102) 또는 음성입력부(103)를 통해 문자와 음성등의 명령이 입력되면, 제어부(105)에서는 해당 명령을 안테나를 통하여 송신할수 있는 신호로 변환하기 위한 제어과정을 수행하여 안테나를 통하여 신호가 송신된다.Looking at the process of transmitting data in the above-described mobile communication terminal, if a command such as text and voice is input through the command input unit 102 or the voice input unit 103, the control unit 105 transmits the corresponding command through an antenna. The signal is transmitted through the antenna by performing a control process for converting the signal into a usable signal.

여기서, 송수신부(101)의 송신부를 살펴보면 도 2와 같다.Here, looking at the transmitter of the transceiver 101 is as shown in FIG.

도 2은 도 1에서 종래 이동통신 단말기의 일반적인 송신부의 일부를 나타낸 블럭도이다.2 is a block diagram illustrating a part of a general transmitter of a conventional mobile communication terminal in FIG. 1.

도시된 바와 같이, 이동통신 단말기의 일반적인 송신부는 전력증폭부(201)와 듀플렉스(203)와 전력증폭부(201)와 듀플렉스(203) 사이에 임피던스를 매칭해 주는 매칭부(202)로 이루어 진다.As shown, a general transmitter of the mobile communication terminal is composed of a power amplifier 201 and a duplex 203 and a matching unit 202 for matching impedance between the power amplifier 201 and the duplex 203. .

여기서, 전력증폭부(201)는 송신신호가 수신되면 해당 송신신호가 듀플렉스(203)에서 손실될 것을 감안하여 적절한 신호의 크기로 증폭한다. Herein, when the transmission signal is received, the power amplifier 201 amplifies the signal to an appropriate signal size in consideration of the loss of the transmission signal in the duplex 203.

듀플렉스(203)는 안테나 하단에 위치하여 송신신호와 수신신호를 분류하여 안테나를 통하여 송신한다.The duplex 203 is located at the bottom of the antenna to classify the transmission signal and the reception signal and transmit the classified signal.

이때, 전력증폭부(201)와 듀플렉스(203)는 매칭부(202)로 매칭되어 있다.In this case, the power amplifier 201 and the duplex 203 are matched with the matching unit 202.

여기서, 매칭부(202)는 서로 다른 두 연결단의 임피던스차에 의한 반사를 줄이기 위하여 사용되는 것으로써, 전력증폭부(201)와 듀플렉스(203) 사이에서 두 연결단 사이의 임피던스 차이를 보정해 준다.Here, the matching unit 202 is used to reduce reflection due to the impedance difference between two different connection terminals, and corrects an impedance difference between the two connection terminals between the power amplifier 201 and the duplex 203. give.

그러나, 전력증폭부(201)와 듀플렉스(203) 사이에서 두 연결단 사이의 임피던스를 매칭해 주는 매칭부(202)로 인해 이동통신 단말기의 부품수가 증가하며, 해당 부품들이 특정한 간격으로 배치되어야 하기 때문에 일정한 공간이 꼭 필요하게 된다.However, the number of parts of the mobile communication terminal increases due to the matching part 202 matching the impedance between the two connection terminals between the power amplifier 201 and the duplex 203, and the parts have to be arranged at specific intervals. Therefore, a certain space is necessary.

또한, 듀플렉스(303)와 전력증폭부(301)가 분리되어 있기 때문에 이동통신 단말기 내에서 듀플렉스(303)와 전력증폭부(301)가 차지하는 공간이 증가되어 이동통신 단말기가 추구하는 소형화면에서 문제를 발생하게 되며, 매칭부(302)로 인한 부품수의 증가는 바로 이동통신 단말기의 단가로 이어져, 가격 경쟁력면에서 문제가 된다. In addition, since the duplex 303 and the power amplifier 301 are separated from each other, the space occupied by the duplex 303 and the power amplifier 301 increases in the mobile communication terminal. The increase in the number of parts due to the matching unit 302 leads directly to the unit price of the mobile communication terminal, which becomes a problem in terms of price competitiveness.

따라서, 이동통신 단말기의 휴대의 용의성을 위하여 필요한 이동통신 단말기의 소형화, 경량화, 저전력화 면에서 비효율적이다.Therefore, it is inefficient in terms of miniaturization, light weight, and low power of the mobile communication terminal which is necessary for the portability of the mobile communication terminal.

이러한 종래기술의 문제점을 해결하기 위한 본 발명의 목적은, 듀플렉스 및 전력 증폭부가 단일칩으로 구성하는 데 있다.An object of the present invention for solving the problems of the prior art is to configure the duplex and the power amplification unit in a single chip.

본 발명의 다른 목적은, 듀플렉스와 전력 증폭부 사이의 매칭부의 제거를 통하여 부품수를 줄이는 데 있다.Another object of the present invention is to reduce the number of components by removing the matching portion between the duplex and the power amplifier.

이와 같은 목적을 달성하기 위한 본 발명은, 전력증폭부, 매칭부와 듀플렉스를 포함하는 이동통신 단말기의 송신부에 있어서, 상기 전력증폭부와 듀플렉스는 일체형으로 형성되는 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the power amplifier and the duplex in the transmitting unit of the mobile communication terminal including a power amplifier, matching unit and duplex is formed integrally.

이에 따르면, 전력증폭부와 듀플렉스가 분리되어 발생하는 공간을 줄일 수 있으며, 전력증폭부와 듀플렉스 사이의 매칭부가 제거되어 이동통신 단말기의 송신부 부품수를 줄일 수 있다.Accordingly, the space generated by separating the power amplifier and the duplex can be reduced, and the matching unit between the power amplifier and the duplex can be removed, thereby reducing the number of components of the transmitter of the mobile communication terminal.

또한, 상기 일체형으로 형성된 전력증폭부와 듀플렉스간에는 매칭회로가 포함되는 것을 특징으로 한다.In addition, a matching circuit is included between the power amplifier and the duplex formed integrally.

이에 따르면, 종래의 이동통신 단말기의 송신부에서 전력증폭부와 듀플렉스사이의 매칭부로 인한 공간의 제약을 줄이면서, 전력증폭부와 듀플렉스사이에 임피던스를 보정해 줄 수 있다.Accordingly, the impedance of the power amplifier and the duplex can be corrected while reducing the constraint of the space caused by the matching unit between the power amplifier and the duplex in the transmitter of the conventional mobile communication terminal.

따라서, 종래의 이동통신 단말기의 송신부에 비해 회로가 간략화되고 저전력화될 수 있다.Therefore, the circuit can be simplified and reduced in power compared with the transmitter of the conventional mobile communication terminal.

본 발명에 따른 전력 증폭부와 듀플렉스가 단일칩으로 구성된 이동통신 단말기의 송신부 모듈을 도면을 참조하여 상세하게 설명한다.A transmitter module of a mobile communication terminal in which a power amplifier and a duplex are configured as a single chip according to the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 의한 전력증폭부가 일체로 구비된 듀플렉스를 나타낸 사시도이다.3 is a perspective view showing a duplex having an integrated power amplifier according to the present invention.

도시된 바와 같이, 전력증폭부와 듀플렉스(301e)가 하나의 적층구조물에 패키지화되어 단일부품으로 형성된다.As shown, the power amplifier and the duplex 301e are packaged in one laminate to form a single component.

구동 증폭기(301a)는 상향주파수 혼합기(도시하지 않음)에서 출력된 신호를 이용하여 전력증폭기(301c)가 충분히 증폭할 수 있도록 최적의 신호를 만든다.The driving amplifier 301a makes an optimal signal so that the power amplifier 301c can amplify sufficiently using the signal output from the uplink mixer (not shown).

전력 증폭기(301c)는 송신신호가 듀플렉스(301e)에서 손실될 것을 감안하여 적절한 신호의 크기로 증폭한다.The power amplifier 301c amplifies to an appropriate signal size in consideration of the loss of the transmission signal in the duplex 301e.

여기서 구동 증폭기(301a)와 전력 증폭기(301c)는 전력증폭부에 포함되는 것으로 구동 증폭기(301a)와 전력 증폭기(301c)는 제1매칭회로(301b)로 매칭되어 있고, 전력 증폭기(301c)와 듀플렉스(301e)는 제2매칭회로(301d)로 매칭되어 임피던스를 보정한다.Here, the driving amplifier 301a and the power amplifier 301c are included in the power amplifier, and the driving amplifier 301a and the power amplifier 301c are matched with the first matching circuit 301b, and the power amplifier 301c The duplex 301e is matched with the second matching circuit 301d to correct the impedance.

따라서, 전력증폭기부와 듀플렉스의 사이에서 서로 다른 두 연결단의 임피던스차에 의한 반사를 줄이기 위해 사용되었던 소자인 매칭부가 제거됨으로써 부품수가 줄어들고, 전력증폭부와 듀플렉스를 단일칩으로 구성하여 기존의 전력증폭부와 듀플렉스가 따로 분리되어 있음으로 인해 발생되었던 공간의 제약을 줄일 수 있다.Therefore, the number of parts is reduced by eliminating the matching part, which is a device used to reduce reflection due to the impedance difference between the two different connection terminals between the power amplifier part and the duplex, and the power amplifier and the duplex are composed of a single chip, thereby reducing power consumption. Since the amplification unit and the duplex are separated separately, the space constraint generated can be reduced.

또한, 단일칩으로 구성된 전력증폭부와 듀플렉스는 그라운드 라인과 전원라인등을 공통으로 사용하게 되어, 신호라인을 줄이고, 전력소모를 줄일 수 있다.In addition, the single-chip power amplifier and duplex share ground lines and power lines in common, reducing signal lines and reducing power consumption.

본 발명에 따르면, 이동통신 단말기의 송신부에서 전력증폭부와 듀플렉스를 단일칩으로 구성하여 공간의 제약을 줄일 수 있다.According to the present invention, a space amplification can be reduced by configuring the power amplifier and the duplex in a single chip in the transmitter of the mobile communication terminal.

또한, 전력증폭부와 듀플렉스 사이의 매칭부의 제거로 인하여 이동통신 단말기의 부품수를 줄일 수 있다.In addition, the number of parts of the mobile communication terminal can be reduced by removing the matching part between the power amplifier and the duplex.

또한, 전력증폭부와 듀플렉스의 그라운드 라인과 전원라인등을 공통으로 사용함으로써 회로가 간략화되고 저전력화될 수 있다.In addition, the circuit can be simplified and reduced in power by using the power amplifier, the duplex ground line and the power line in common.
