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

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
