Functional Diagram
General Description
The HMC737LP4(E) is a GaAs InGaP Heterojunction
Bipolar Transistor (HBT) MMIC VCO. The
HMC737LP4(E) integrate a resonator, negative
resistance device, varactor diode and feature half
frequency output. The VCO’s phase noise performance
is excellent over temperature, shock, and process due
to the oscillator’s monolithic structure. Power output
is +9 dBm typical from a +4.2V supply voltage. The
voltage controlled oscillator is packaged in a leadless
QFN 4x4 mm surface mount package, and requires no
external matching components.
