Abstract

This paper presents a K-band balanced RTD-based MMIC VCO with extremely low power consumption. In order to reduce the power consumption, an InP-based RTD is used for microwave power generation. The K-band VCO generates an RF output power of -17.7 dBm at a DC power of 1.0 mW. A wide tuning range of 2.1 GHz is obtained by using the base-collector junction of the integrated HBT as a varactor. In addition, a low phase noise of -108 dBc/Hz at 1 MHz offset at 22.2 GHz has been obtained
