Functional Diagram
General Description
The HMC429LP4 is a GaAs InGaP Heterojunc-
tion Bipolar Transistor (HBT) MMIC VCO with
integrated resonator, negative resistance device,
varactor diode, and buffer amplifier. Covering
4.45 to 5.0 GHz, the VCO’s phase noise per-
formance is excellent over temperature, shock,
vibration and process due to the oscillator’s
monolithic structure. Power output is 4.0 dBm
typical from a single supply of 3.0V @ 30mA.
The voltage controlled oscillator is packaged in a
low cost leadless QFN 4 x 4 mm surface mount
package.
