Functional Diagram
General Description
The HMC735LP5(E) is a GaAs InGaP Heterojunc-
tion Bipolar Transistor (HBT) MMIC VCO. The
HMC735LP5(E) integrates resonators, negative
resistance devices, varactor diodes and features a
divide-by-4 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 +17 dBm typical from a
+5V supply voltage. The prescaler function can be dis-
abled to conserve current if not required. The voltage
controlled oscillator is packaged in a leadless QFN
5x5 mm surface mount package, and requires no
external matching components.
