초록

본 논문에서는 혼합기의 IF 대역폭을 향상시키는 방법을 제안하며, 이를 적용하여 설계 제작된 0.13-${\mu}m$ RFCMOS 공정 기반 24 GHz 하향 변환 혼합기의 결과를 보인다. 측정 결과, 본 혼합기는 24 GHz의 LO 주파수에 대해 DC부터 5.25 GHz까지의 IF 주파수에서 $2.7{\pm}1.5$ dB의 변환 이득을 보이며, P-1dB와 LO-RF isolation은 각각 -8.7 dBm과 21 dB로 나타났다. 본 혼합기는 1.3 V의 전원으로부터 10.6 mA의 DC 전류를 소모한다.

In this work, a wideband technique has been proposed that improves the IF bandwidth of mixers and a 24-GHz down-conversion mixer employing the proposed technique has been designed and fabricated based on 0.13-${\mu}m$ RFCMOS technology. The mixer showed the conversion gain of $2.7{\pm}1.5$ dB from DC to 5.25 GHz IF for a fixed LO frequency of 24 GHz. Measured P-1dB and LO-RF isolation was -8.7 dBm and 21 dB, respectively. The mixer draws DC current of 10.6 mA from 1.3 V supply.
