본 고안은 HF, VHF, UHF, Microwave 주파수 대역의 이동통신 전화 페이징(paging)고주파를 전송하는 장치에 관한 것이다.The present invention relates to an apparatus for transmitting a paging high frequency mobile communication telephone in the HF, VHF, UHF, Microwave frequency band.
현재 국내 이동통신 기지국 현황은 4 콤바이너(합성장치)를 사용하여 고주파 송신기 4 채널을 1개 안테나로 송신하고 있으며, 1개 기지국에 40개 고주파를 송신할 경우 4 콤바이너 10개와 안테나 10개를 필요로 한다. 그러나 이러한 경우 안테나를 부착할 장소가 여의치 않으며, 부착한다 해도 근접되어 실시되는 여러개의 안테나의 상호 간섭에 의하여 불량한 전파송신을 초래하게 된다.The current state of mobile communication base stations in Korea is using 4 combiners (synthesizers) to transmit 4 channels of high frequency transmitters with 1 antenna, and 4 combiners 10 and antenna 10 when 40 high frequencies are transmitted to 1 base station. I need a dog. However, in such a case, the place to attach the antenna is not available, and even if it is attached, poor radio wave transmission is caused by mutual interference of several antennas which are performed in close proximity.
이에 본 고안은 이러한 문제점을 해결하기 위한 것으로, 안테나 1개에 여러 채널을 고주파 송 수신하는 장치로써, 안테나 1개에 많은 고주파 채널 전송이 필요한 이동통신용 전송장치에 사용하는 것을 목적을 한다.Accordingly, the present invention is to solve this problem, it is an apparatus for receiving a high frequency transmission and reception of several channels in one antenna, the purpose of the use in a mobile communication transmission device that requires a large number of high frequency channel transmission in one antenna.
본 장치의 대략적인 구성은 제1도에서 보듯이, 2개 이상의 소채널(1-n CH)송신(수신) 콤바이너[1],[2],[3].....[m]을 최종 합성기 (5)에 결합함으로써, 결과적으로 (T1+T2+...+Tn)×m개 채널의 많은 고주파를 1개 안테나 또는 전송로에 연결한다.The schematic configuration of this apparatus is shown in Fig. 1, as shown in Fig. 1, in which two or more small channel (1-n CH) transmit (receive) combiners [1], [2], [3] ..... [m ] Is coupled to the final synthesizer (5), which in turn connects many high frequencies of (T1 + T2 + ... + Tn ) × m channels to one antenna or transmission path.
제1도는 본 고안장치의 전체적인 구성을 나타낸 것으로써, 소채널 송신(수신)콤바이너의 구성을 살펴보면, T1에 입력되는 고주파는 아이소레이터(1)을 거쳐서 캐비티(2)를 통하여 동축케이블(3)을 이용하여 합성기(4)에 입력된다. 캐비티(2)는 해당 주파수 T1에 만 동조되어 타 주파수의 통과를 저지한다. 이때 합성기(4)는 다른 채널인 T2....Tn와 결합하여 1개 출력을 송출한다. 나머지 T2....Tn도 T1과 마찬가지 방법으로 결합하여 송출시킨다.Figure 1 shows the overall configuration of the device of the present invention, when looking at the configuration of the small-channel transmission (receiver) combiner, the high frequency input to T1 through the cavity 2 through the isolator 1 (coaxial cable ( 3) is input to the synthesizer (4). The cavity 2 is tuned only to the corresponding frequency T1 to block passage of other frequencies. At this time, the synthesizer 4 combines with another channel T2 .. Tn and outputs one output. The remaining T2 .... Tn is also combined and sent out in the same way as T1 .
이와 같은 방법으로 T1T2....Tn이 결합된 여러개의 합성기(4)로부터 송출되는 고주파는 다시 최종합성기(5)에서 결합하여 1개의 전송로 및 안테나에 연결한다.In this way, T1 T2 .. Tn is transmitted from a plurality of synthesizers (4) coupled to the final synthesizer (5) is coupled to one transmission path and the antenna is connected.
이때, [1],[2],[3],...[m]의 고주파 송신(수신) 주파수 T1T2....Tn은 서로 다른 주파수를 사용하여야 하며, 주파수 간격을 상호 간섭되지 않게 100KHz 이상 이격시켜야 한다. 예를 들어 200KHz, 160MHz 이격시킬경우 채널 용량에 따라 삽입 손실이 2~3db이하이다. 일반적으로 주파수가 낮으면 간격 100KHz이하로 좁하져도 되지만 주파수가 UHF. Microwave대로 높아지면 주파수 간격이 넓어진다.At this time, the high frequency transmission (reception) frequencies T1 T2 .... Tn of [1], [2], [3], ... [m] must use different frequencies and mutually interfere the frequency interval. It should be spaced over 100KHz. For example, if the 200KHz, 160MHz spaced apart, the insertion loss is less than 2 ~ 3db depending on the channel capacity. In general, if the frequency is low, the frequency can be narrowed to less than 100 KHz, but the frequency is UHF. The higher the microwave, the wider the frequency interval.
또한, 제2도는 제1도에서 본 장치에서 주요한 역할을 하는 캐비티 부분을 상세히 나타낸 것으로, 캐비티(2)내부에 이마봉(8)을 삽입함으로써 온도 보상 효과가 있음과 동시에 주파수 조정이 가능하고 또한, 온도 보상형 동관은 캐비티(2) 상단에 부착하여 온도변화에도 안정하여 주파수 특성이 변하지 않게 하엿다.In addition, FIG. 2 shows in detail the cavity part which plays a major role in the apparatus in FIG. 1, and by inserting the forehead 8 into the cavity 2, temperature compensation effect and frequency adjustment are possible. The temperature compensated copper tube was attached to the top of the cavity 2 so that it was stable even with temperature changes so that the frequency characteristics did not change.
본 장치의 원리를 상세히 살펴보면 다음과 같다.Looking at the principle of the device in detail as follows.
제1도의 각 합성기(콤바이너)의 원리를 설명하면, 아이소레이터(1)에 입력된 고주파는 캐비티(2)로 반사되고 이 반사파는 아이소레이타(1)에 부착한 의사부하에 흡수하여 고주파 송신장치를 보호한다. 또한, 캐비티(2)는 아이소레이타(1)에 입력된 고주파(T1)만을 통과하고 다른 고주파(T2....Tn)는 통과를 저지하여 합성기(4)에 입력되고, 통과된 고주파는 안테나(전송로)로 합성되어 전송하게 된다. 또한, 최종단의 합성기(5)는 이전의 합성기(4)의 출력을 발생하는 장치로써, 각 입력 동축케이블(3)을 통하여 합성하는데 있어서 캐비티(2) 출력단을 단락하여 합성기(5)에서 보는 임피단스가 최대가 되게 하여 안테나쪽으로 [1],[2],...[m]의 고주파가 전송되도록 한다.Referring to the principle of each synthesizer (combiner) of FIG. 1, the high frequency input to the isolator 1 is reflected to the cavity 2 and the reflected wave is absorbed by the pseudo load attached to the isolator 1 Protect high frequency transmitters. Further, the cavity 2 passes only the high frequency T1 input to the isolator1 and the other high frequencies T2 .. Tn are inputted to the synthesizer 4 by blocking the passage and passed. The high frequency is synthesized by an antenna (transmission path) and transmitted. In addition, the synthesizer 5 of the final stage is a device for generating the output of the previous synthesizer 4, and in synthesizing through each input coaxial cable 3, the output terminal of the cavity 2 is shorted and viewed from the synthesizer 5. Maximize the impedance so that high frequencies of [1], [2], ... [m] are transmitted towards the antenna.
또한 소용량으로 합성시켜 전송할 경우는 [1],[2],[3],...[m]이 서로 독립적으로 소전송이 가능하다. 예를 들면 [1]의 5 CH 합성기(4)개를 최종합성기(5)에 합성시킬 경우 20개 채널의 고주파를 1개의 고주파 전송로 또는 1개 안테나로 전송할 수 있다.In the case of a small capacity synthesized transmission, [1], [2], [3], ... [m] can be small transmission independently of each other. For example, when the 5 CH synthesizers 4 of [1] are synthesized in the final synthesizer 5, the high frequency of 20 channels can be transmitted to one high frequency transmission path or one antenna.
이상 설명한 바와 같이 본 고안은 종래의 소수 채널만을 1개 안테나에 연결하여 전파 송신하는 방식을 개선한 것으로, 안테나 1개에 많은 고주파채널 전송이 요구되는 이동 통신용 전송장치에 효과적으로 이용될 수 있다.As described above, the present invention improves the conventional radio wave transmission method by connecting only a small number of channels to one antenna, and can be effectively used for a mobile communication transmission apparatus requiring many high frequency channel transmissions in one antenna.
