Active frequency doubler, designed for use in the LO Path after VCO to double up the LO frequency

Overview

RFDBL03C is an active frequency doubler, designed for use in the LO Path after VCO to double up the LO frequency within the IC to feed in and drive the mixer. The design utilizes active balun in push configuration and balanced amplifier using 0.1um GaAs pHEMT with high pass matching to attain good fundamental suppression, conversion gain of 1.97 dB at 0 dBm input drive power and good input and output VSWRs. The technology used to design doubler is 0.1um GaAs pHEMT process. Results are shown in datasheet with all parasitics & coupling effects at desired frequency.
