Description

ＧＳＭ/ＧＰＲＳ 및 ＴＤ-ＳＣＤＭＡ를 지원하는 이동통신 단말기{MOBILE COMMUNICATION TERMINAL IN USING GSM/GPRS AND TD-SCDMA}MOBILE COMMUNICATION TERMINAL IN USING GSM / GPRS AND TD-SCDMA}

본 발명은 이동 통신단말기에 관한 것으로, 특히 멀티모드를 수용하면서도 부품수를 줄여서 PCB설계 공간의 축소로 단말기 전체 크기를 축소하도록 한 GSM /GPRS 및 TD-SCDMA를 지원하는 이동통신 단말기에 관한 것이다.The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal supporting GSM / GPRS and TD-SCDMA to reduce the overall size of the terminal by reducing the PCB design space by reducing the number of parts while accommodating the multi-mode.

전세계적으로 이동 단말기의 경향이 2개 이상의 멀티모드(multimode)를 수용하면서도 단말기의 크기는 소형화하는 추세이다.While the trend of mobile terminals in the world accommodates two or more multimodes, the size of the terminals has become smaller.

현재 멀티모드 단말기 중 트리플 모드(Triple Mode)를 적용한 이동 통신단말기가 개발되고 있는데, 상기 트리플 모드가 적용된 이동 통신단말기를 예로 들면, GSM(Global System for Mobile Communications)/GPRS(General Packet Radio Service), WCDMA(Wideband Code Division Multiple Access), CDMA-2000, TD-SCDMA(Time Division-Synchronous Code Divion Multiple Access)를 적용한 중국향 3G 단말기가 있다.Currently, a mobile communication terminal adopting a triple mode among multi-mode terminals is being developed. For example, a mobile communication terminal applied to the triple mode includes, for example, Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS), There are 3G terminals for China that use Wideband Code Division Multiple Access (WCDMA), CDMA-2000, and Time Division-Synchronous Code Divion Multiple Access (TD-SCDMA).

여기서, 도1은 단말기 측면에서, GSM/GPRS와 TD-SCDMA의 주파수 분배 영역을 볼 수 있는데, 상기 GSM/GPRS는 EGSM이라고 불리는 송수신 각각 35MHz대역과 DCS라고 불리는 송수신 각각 75MHz 대역을 할당받고 있다.Here, FIG. 1 shows a frequency distribution area of GSM / GPRS and TD-SCDMA on the side of a terminal. The GSM / GPRS is allocated a 35MHz band each called a EGSM and a 75MHz band respectively called a DCS.

상기 TD-SCDMA는, 현재 중국에서, 55MHz 이상의 대역을 할당받는데, GSM /GPRS와 다른 TDD방식으로 송수신 동일 주파수를 사용하므로 송수신 대역이 분리되지 않는다.The TD-SCDMA is currently allocated a band of 55 MHz or higher in China, and since the same transmission / reception frequency is used in a TDD scheme different from GSM / GPRS, the transmission / reception band is not separated.

두가지 방식을 적용하는 단말기의 경우, 안테나는 공유되고, 그 안테나로부터 수신되는 신호를 분리하기 위하여 스위치등을 사용하나, 이러한 부품의 추가는 단말기의 RF부분의 설계시, 삽입손실을 증가시켜 송신전력 효율 및 수신감도를 저하시킨다.In the case of the terminal adopting the two methods, the antenna is shared and a switch is used to separate the signal received from the antenna, but the addition of these components increases the transmission power by increasing the insertion loss in the design of the RF part of the terminal. Decreased efficiency and reception sensitivity.

또한, 부품의 추가는 단말기 설계시 PCB공간 확보에 어려움을 줄뿐만 아니라 비용을 증가시키고, 생산수율 및 고장율에도 나쁜 영향을 미친다.In addition, the addition of components not only makes it difficult to secure the PCB space in the terminal design, but also increases the cost and adversely affects the production yield and failure rate.

따라서, 단말기의 RF부분을, 도2와 같이 RF수신모듈(1)과 RF송신모듈(2)로 온칩화하거나(CASE2), 송신부의 전력증폭기(3)를 포함하여 RF 송신모듈(2)을 온칩화하고 있다(CASE1).Accordingly, the RF portion of the terminal is on-chip into the RF receiving module 1 and the RF transmitting module 2 as shown in FIG. 2 (CASE2), or the RF transmitting module 2 including the power amplifier 3 of the transmitting unit. It is on-chip (CASE1).

그러나, 상기 전력증폭기 이후 단부터 저전력증폭기까지의 부품들은 수동소자로 이루어져 IC형태로 만들기 어렵고, 송신단의 전력증폭기 다음단으로부터 안테나까지의 삽입손실과 수신단의 안테나에서부터 저잡음증폭기 전단까지의 삽입손실은 수신감도와 송신전력 효율을 저하시키는 문제점이 있다.However, the parts from the power amplifier to the low power amplifier after the power amplifier are made of passive elements, making it difficult to form an IC. The insertion loss from the power amplifier of the transmitting end to the antenna and the insertion loss from the antenna of the receiver to the front of the low noise amplifier are received. There is a problem of lowering the sensitivity and the transmission power efficiency.

따라서, 상기와 같은 문제점을 감안하여 창안한 본 발명은, 멀티모드를 수용하면서도 부품수를 줄여서 PCB설계 공간의 축소로 단말기 전체 크기를 축소하도록 한 GSM/GPRS 및 TD-SCDMA를 지원하는 이동통신 단말기를 제공함에 그 목적이 있다.Accordingly, the present invention, which was devised in view of the above problems, is a mobile communication terminal supporting GSM / GPRS and TD-SCDMA which reduces the overall size of the terminal by reducing the PCB design space by accommodating the multi-mode while reducing the number of parts. The purpose is to provide.

또한, GSM/GPRS모드에서의 송신시, 오프셋 피엘엘 구조를 이용하여 대역 통과 필터링 기능을 구현함으로써, 단말기 RF성능 저하의 원인이 되는 RF프런트 엔드 삽입손실을 감소시키도록 한 GSM/GPRS 및 TD-SCDMA를 지원하는 이동통신 단말기를제공함에 그 목적이 있다.In addition, GSM / GPRS and TD- are designed to reduce RF front end insertion loss, which causes degradation of RF performance, by implementing band pass filtering using offset PLL structure when transmitting in GSM / GPRS mode. It is an object of the present invention to provide a mobile communication terminal supporting SCDMA.

The RF processed signal is transmitted to the base station through the SPDT switch, the SP4T switch, and the antenna.

만약, 송신시 TD-SCDMA모드이면, SPDT스위치와 SP4T스위치가 송신 TD-SCDMA 경로측으로 절환되고, 송신TD-SCDMA RF모듈(50)은 모뎀칩(10)으로부터 입력되는 기저대역의 신호를 RF처리하여 그 RF 처리된 신호를 상기 SPDT스위치와 SP4T스위치 및 안테나를 통해 기지국으로 송신한다.If the transmission mode is TD-SCDMA mode, the SPDT switch and the SP4T switch are switched to the transmission TD-SCDMA path side, and the transmission TD-SCDMA RF module 50 RF-processes the baseband signal input from the modem chip 10.
