HMC533LP4 / 533LP4E
MMIC VCO w/ DIVIDE-BY-16,

General Description
Features
Functional Diagram
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.
Pout: +12 dBm
Phase Noise: -95 dBc/Hz @100 KHz Typ.
No External Resonator Needed
Single Supply: +5V @ 220 mA
24 Lead 4x4mm QFN Package: 9 mm
Typical Applications
Low noise MMIC VCO w/Divide-by-16 for:
• VSAT Radio
• Point to Point/Multipoint Radio
• Test Equipment & Industrial Controls
• Military End-Use
• Automotive Radar
