General Description

Features

Functional Diagram

The HMC506LP4 & HMC506LP4E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs

with

integrated

resonators,

negative

resistance

devices,

varactor

diodes,

and

buffer

amplifiers.

Covering 7.8 to 8.7 GHz, the VCO’s phase noise

performance is excellent over temperature, shock

and vibration due to the oscillator’s monolithic struc-

ture. Power output is +14 dBm typical from a single

supply of +3.0V @ 77 mA. The voltage controlled

oscillator is packaged in a leadless QFN 4 x 4 mm

surface mount package.

Pout: +14 dBm

Phase Noise: -103 dBc/Hz @100 KHz

No External Resonator Needed

Single Supply: +3V @ 77 mA

Typical Applications

Low noise MMIC VCO w/Buffer Amplifier for:

• VSAT Radio

• Point to Point/Multipoint Radio

• Test Equipment & Industrial Controls

• Military End-Use
