Abstract :
This paper describes 3 types of free running oscillators that have been designed and fabricated using a 0.5 micron HEMT process. Output powers, including the waveguide transition, of -3 to -5 dBm have been measured in Q band. One type of oscillator, exhibits an external Q greater than 2700 at 52 GHz. The design approaches and the results, on phase noise in particular, are discussed.
