Functional Diagram
General Description
The HMC391LP4 & HMC391LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs
with integrated resonators, negative resistance
devices, varactor diodes, and buffer amplifiers.
Covering 3.9 to 4.45 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 5.0 dBm typical from a
single supply of +3V @ 30 mA. The voltage controlled
oscillator is packaged in a low cost leadless QFN 4 x 4
mm surface mount package.
