General Description

The HMC401QS16G is a GaAs InGaP Hetero junction Bipolar Transistor (HBT) MMIC VCO. The HMC401QS16G integrates a resonator, negative resistance device, varactor diode and divide-by-8 prescaler. The VCO’s phase noise performance is excellent over temperature, shock, and process due to the oscillator’s monolithic structure. Power output is -7 dBm typical from a 5V supply voltage. The voltage controlled oscillator is packaged in a low cost, surface mount 16 leaded QSOP package with an exposed base for improved RF and thermal performance.
