Abstract :
This paper describes the design approach, fabrication process, and performance of a monolithic CPW oscillator incorporating a buffer amplifier on the same chip, for K-band wireless network applications. At 21 GHz, the output power of the oscillator recorded 17 dBm with an overall DC-RF efficiency of 22%. By changing the length of a source feedback line, the oscillation frequency was varied up to 26 GHz. For all cases, the output power remained higher than 16 dBm.<>
