摘要：

An 18 GHz coplanar waveguide (CPW) monolithic voltage controlled oscillator (VCO) has been demonstrated using InAlAs/InGaAs HBT technology, The VCO achieves 6% frequency tuning range using a varactor diode constructed from the HBT base emitter junction, A CPW design was employed to increase the Q-factor of the monolithic resonator as well as reduce the chip size, The VCO obtains an output power of +10 +/- 0.5 dBm over the tuning range and a collector efficiency of 11.5%. A SSB phase noise of -72 and -96 dBc/Hz at 100 kHz and 1 MHz offset frequency from the carrier were achieved, respectively, This represents the first reported phase noise results of an InAlAs/InGaAs-based HBT VCO with a monolithic integrated varactor and are comparable to other MMIC HBT varactor-tuned VCO's reported in this frequency band.
