Abstract
This paper presents a design of high power oscillator using a spiral resonator and high power transistor with measurement. Even lots of drawbacks are known in design of oscillators using high power transistors, the spiral resonator is adopted because it has relatively high Q out of planar resonators. The designed power oscillator at 1.8GHz is fabricated and tested. Measurement shows the obtained output power is 23.5dBm at 1.74GHz with -146.76dBc/Hz of phase noise at 1MHz offset. In addition, it is illustrated that the frequency stability is excellent with the shift less than 1MHz and the measured maximum output power is around 24dBm when the bias voltages are adjusted.
