Title:
A Hybrid Fabricated 40 GHz Low Phase Noise Sige Push-Push Oscillator 
Abstract:
We present a 40 GHz push-push oscillator based on SiGe HBTs. The circuit is fabricated in thin film technology on an alumina substrate. It provides an output power of -9 dBm at 40 GHz and two differential outputs with -6 dBm each at the fundamental frequency of 20 GHz. The oscillator shows an excellent phase noise performance and reaches -108 dBc/Hz at the second harmonic frequency of 40 GHz and -114 dBc/Hz at the fundamental frequency of 20 GHz Both values are measured at an offset frequency of...    »
