Abstract
A fully integrated voltage controlled oscillator (VCO) MMIC for millimeter-wave applications has been designed and implemented in InGaP/GaAs heterojunction bipolar transistor (HBT) technology. To achieve a fully integrated VCO, a base-emitter diode is employed as the tuning varactor, and microstrip lines are employed for the transmission lines. The fabricated VCO MMIC chip size is 0.86 mm × 1.34 mm and delivers an output power of 5.1 dBm at 28.7 GHz and a free-running phase noise of -118 dBc/Hz at 1 MHz offset. The dc current consumption is only 20 mA.
