Functional Diagram
General Description
The HMC533LP4 & HMC533LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC
VCOs. The HMC533LP4 & HMC533LP4E integrate
resonators, negative resistance devices, varactor
diodes and feature a divide-by-16 output. The VCO’s
phase noise performance is excellent over temperature,
shock, and process due to the oscillator’s monolithic
structure. Power output is +12 dBm typical from a +5V
supply voltage. Prescaler function can be disabled to
conserve current if not required. The voltage controlled
oscillator is packaged in a leadless QFN 4 x 4 mm
surface mount package.
