Abstract

A semidynamic frequency divide-by-1.5 MMIC comprises a tunable polyphase filter, tunable image-rejection mixer, and a static divide-by-2 in the feedback path. Wideband suppression of unwanted tones is achieved by employing a tunable image-rejection mixer and a tunable single-stage polyphase filter. Implemented in GaInP/GaAs HBT technology, the divide-by-1.5 MMIC operates over the input frequency range of 4.5 to 9.2 GHz with better than -20 dBc suppressions of $1/3{\times}f_{in}\;and\;f_{in}$ tones, while dissipating 29 mA from 4.1 V supply.

마이크로파 광대역 능동 주파수 분주기는 가변 위상 변환기(tunable polyphase filter)와 가변 영상 주파수 제거 혼합기(tunable image-rejection mixer)를 연결한 것에 정적 이분 주기(static divide-by-2)를 궤환 경로로 연결하여 구성하였다. 출력에서 원하지 않는 불요파 신호를 영상주파수 제거 혼합기와 가변 위상 변환기를 조정함으로써 넓은 주파수 영역에서 제거할 수 있었다. GaInP/GaAs HBT 공정을 이용하여 설계된 1.5 분주비를 갖는 주파수 분주 회로는 4.5 GHz에서 9.2 GHz의 광대역 입력 주파수 영역에서 동작하였으며, $1/3{\times}f_{in}$과 $f_{in}$ 불요파 성분이 모두 -20 dBc 이하로 억제되었다. 소모 전력은 4.1 V에서 29 mA이다.
