Abstract
In this paper, we present the design of a MMIC circuit, which contains two switched VCOs based on the Clapp topology using a UMS GaInP/GaAs HBT technology. This achieves more than 30% of tuning range around 3.2 GHz, a phase noise of -95 dBc/Hz at 100 KHz offset frequency from the carrier and a power consumption of 150 mW. A DC switch based on HBT was used in order to switch between the 2 VCOs.
