Functional Diagram
General Description
The HMC506LP4 is a GaAs InGaP Heterojunc-
tion Bipolar Transistor (HBT) MMIC VCO with
integrated resonator, negative resistance device,
varactor diode, and buffer amplifier. Covering
7.8 to 8.7 GHz, the VCO’s phase noise perfor-
mance is excellent over temperature, shock and
vibration due to the oscillator’s monolithic struc-
ture. Power output is +14 dBm typical from a
single supply of +3.0V @ 77 mA. The voltage
controlled oscillator is packaged in a leadless
QFN 4 x 4 mm surface mount package.
