Abstract
A simple scheme for enhancing the locking range and capture range of MESFET VCOs is presented using a low frequency DC-coupled amplifier. This circuit is based on phase-locked loop (PLL) techniques; in the present case the MESFET VCO also provides the function of a mixer or phase detector. A 10 GHz prototype was constructed which demonstrated a locking range more than double that of the isolated VCO injection-locking range over the same range of injected signal power.
