General Description

The HMC358MS8G is a GaAs InGaP Hetero­junction Bipolar Transistor (HBT) MMIC VCO. The
HMC358MS8G integrates a resonator, negative
resistance device, varactor diode, and buffer
amplifi er. The VCO’s phase noise performance is
excellent over temperature, shock, and process
due to the oscillator’s monolithic structure. Power
output is 11 dBm typical from a 3.0V supply volt­age. The voltage controlled oscillator is packaged
in a low cost, surface mount 8 lead MSOP pack­age with an exposed base for improved RF and
thermal performance.
