초록

마이크로스트립 선로의 접지면에 슬롯이 있는 SGPS (Split Ground Plane Structure) 구조는 등가적으로 병렬공진 특성을 갖는다. 슬롯의 길이가 특정 주파수의 반파장과 같으면 큰 감쇠특성을 나타낸다. 본 연구에서는 SGPS 구조의 슬롯 중앙에 저항을 두고 저항 값을 가변하면 공진주파수에서 감쇠특성이 변하는 원리를 이용하여 MMIC용 가변 감쇠기를 설계하였다. 이 감쇠기에서 저항대신 PIN 다이오드를 이용하면 송수신기에서 자동이득조절 (AGC) 회로에 응용할 수 있다.

In this paper, the electric characteristic of the SGPS with slot in the ground plane is similar to the parallel resonant circuit. When the slot length in SGPS is equal to the half wavelength of specific frequency, the characteristic of SGPS represent the large attenuation at the specific frequency. We found out the relation between attenuation and resistor on the slot in SGPS and we designed the variable attenuator for MMIC using the variable resistor. This attenuator can be applied to AGC circuit in transceiver if the PIN diode is used replace for resistor.
