본 고안은 BS방송 수신용 LNB 등에 사용되는 유전체 공진 발진기에 관한 것이다.The present invention relates to a dielectric resonator oscillator used in LNB for BS broadcast reception.

초 고주파 대역의 발진 회로는 안정성 특성을 향상시키고 저 가격으로 제작하기 위해 보통 유전체 공진자 발진기(DRO : Dielectric Resonated Oscillator)가 많이 사용되고 있다.In the high frequency band oscillator circuit, a dielectric dielectric oscillator (DRO) is commonly used to improve stability characteristics and to manufacture a low price.

이러한 DRO는 Q가 큰 유전체 공진자를 발진용 FET의 게이트단에 설계된 마이크로 스트립 선로에 결합시켜 구성하는 반사형의 회로가 일반적이다.Such a DRO is generally a reflective circuit composed of a large Q dielectric resonator coupled to a microstrip line designed at the gate end of the oscillation FET.

이 반사형DRO에서 유전체 공진자와 마이크로 스트립과의 결합력은 매우 중요하며 이에 따라 발진특성이 좌우된다.In this reflective type DRO, the coupling force between the dielectric resonator and the microstrip is very important and thus the oscillation characteristics are influenced.

종래에는 항상 일정한 위치에 유전체 공진자가 놓이도록 다양한 지그를 이용하게 되는데 테프론 PCB상에 지그를 형성하는것부터 쉽지않은 일이며 더나아가 해당 위치에 유전체 공진자를 정확히 배치하는 작업도 상당히 까다로웠다. 즉, 유전체 공진자와 마이크로 스트립 선로는 제2도에서 나타내고 있는바와 같이 어떠한 특정거리(d)를 유지할때 최대의 결합력을 얻을 수 있게 되는데 발진기 조립공정상 그러한 최적 위치에 유전체 공진자를 배치하기란 지금가지는 매우 힘들었다.Conventionally, various jigs are used so that dielectric resonators are always placed at a certain position, but it is not easy to form a jig on a Teflon PCB, and furthermore, precisely placing a dielectric resonator at a corresponding position was quite difficult. That is, as shown in FIG. 2, the dielectric resonator and the micro strip line can obtain the maximum coupling force when maintaining a certain distance d. In the oscillator assembly process, the dielectric resonator is placed at such an optimal position. It was very hard.

본 고안은 마이크로 스트립 선로와 유전체 공진자의 이격 거리를 일정하게 유지할 수 있게 되며, 또한 조립작업을 편리하게 한다.The present invention can maintain a constant distance between the microstrip line and the dielectric resonator, and also facilitates the assembly work.

본 고안의 특징은 유전체 공진자가 배치될 위치에 반원형상의 패턴을 테프론 PCB상에 미리 형성하여 준다는데 있다.A feature of the present invention is that a semicircular pattern is formed on a Teflon PCB in advance at a position where a dielectric resonator is to be disposed.

이하 도면을 참고로 하여 본 고안을 설명한다.Hereinafter, the present invention will be described with reference to the drawings.

제1도에서 도시하고 있는 바와같이 마이크로 스트립 선로(11)와 유전체 공진자(15)의 결합력이 최대로 되는 거리(d)를 확보하기 위해 컴퓨터 시뮬레이션을 통한 반원형 패턴(16)의 위치를 결정하고, 이를 테프론 PCB상에 형성한다.As shown in FIG. 1, the position of the semi-circular pattern 16 is determined by computer simulation in order to secure a distance d at which the coupling force between the micro strip line 11 and the dielectric resonator 15 is maximized. This is formed on a Teflon PCB.

도면중 13은 발진 FET, 12는 피이드백회로, 14는 출력매칭회로, 17은 발진출력단자를 나타내고 있다.In the figure, 13 is an oscillation FET, 12 is a feedback circuit, 14 is an output matching circuit, and 17 is an oscillation output terminal.

따라서 마이크로 스트립 선로(11)가 형성된 테프론 PCB상에 상기 마이크로 스트립 선로(11)에 최적의 거리(d)로 인접하여 유전체 공진자(15)를 조립 배치할때, 상기 반원형 패턴(16) 내부호에 유전체 공진자(15)의 둘레의 반을 일치시켜 배치하면 항상 최적의 거리(d)를 유지시켜 줄수 있게되므로, 본 고안에 따라 유전체 발진기를 구성하게 되면 안정되고 일정한 최대발진출력을 용이한 조립공정을 통하여 얻을 수 있게 된다.Therefore, when the dielectric resonator 15 is assembled and disposed adjacent to the microstrip line 11 at an optimal distance d on the Teflon PCB on which the microstrip line 11 is formed, the internal arc of the semi-circular pattern 16 is disposed. If the half of the periphery of the dielectric resonator 15 is aligned with each other, the optimum distance d can be maintained at all times. It can be obtained through the process.
