Title:
A 50 GHz SiGe HBT Push-Push Oscillator 
Abstract:
We present a 50 GHz push-push oscillator fabricated in thin film technology on an alumina substrate using silicon-germanium HBTs. Output power of the oscillator is -5.6 dBm with a suppression of the fundamental and the second harmonic signal of -40 dBc and -38 dBc, respectively. Measured phase noise of the oscillator is -98 dBc at an offset frequency of 1 MHz
