MMIC VCO w/ BUFFER

AMPLIFIER, 3.55 - 3.9 GHz

v01.0604

General Description

Features

Functional Diagram

The

HMC390LP4

is

a

GaAs

InGaP

Heterojunction Bipolar Transistor (HBT) MMIC

VCO

with

integrated

resonator,

negative

resistance device, varactor diode, and buffer

amplifier. Covering 3.55 to 3.9 GHz, the VCO’s

phase noise performance is excellent over

temperature, shock, vibration and process due

to the oscillator’s monolithic structure.

Power

output is 4.7 dBm typical from a single supply of

3V @ 42 mA. The voltage controlled oscillator is

packaged in a low cost leadless QFN 4 x 4 mm

surface mount package.

Pout: +4.7 dBm

Phase Noise: -112 dBc/Hz @100 KHz

No External Resonator Needed

Single Supply: 3V @ 42 mA

Typical Applications

Low noise MMIC VCO w/Buffer Amplifier for:

• Wireless Local Loop (WLL)

• VSAT & Microwave Radio

• Test Equipment & Industrial Controls

• Military
