Functional Diagram
General Description
The HMC390LP4 is a GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC
VCO with integrated resonator, negative
resistance device, varactor diode, and buffer
amplifier. Covering 3.55 to 3.9 GHz, the VCO’s
phase noise performance is excellent over
temperature, shock, vibration and process due
to the oscillator’s monolithic structure. Power
output is 4.7 dBm typical from a single supply of
3V @ 42 mA. The voltage controlled oscillator is
packaged in a low cost leadless QFN 4 x 4 mm
surface mount package.
