Functional Diagram
General Description
The HMC533LP4 & HMC533LP4E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs.
The HMC533LP4 & HMC533LP4E integrate resona-
tors, negative resistance devices, varactor diodes and
feature a divide-by-16 output. T he 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 con-
serve current if not required. The voltage controlled
oscillator is packaged in a leadless QFN 4 x 4 mm
surface mount package.
