MMIC VCO w/ BUFFER

AMPLIFIER, 4.45 - 5.0 GHz

v01.0604

General Description

Features

Functional Diagram

The HMC429LP4 is a GaAs InGaP Heterojunc-

tion Bipolar Transistor (HBT) MMIC VCO with

integrated resonator, negative resistance device,

varactor diode, and buffer amplifier.

Covering

4.45 to 5.0 GHz, the VCO’s phase noise per-

formance is excellent over temperature, shock,

vibration and process due to the oscillator’s

monolithic structure. Power output is 4.0 dBm

typical from a single supply of 3.0V @ 30mA.

The voltage controlled oscillator is packaged in a

low cost leadless QFN 4 x 4 mm surface mount

package.

Pout: +4.0 dBm

Phase Noise: -105 dBc/Hz @100 KHz

No External Resonator Needed

Single Supply: 3V @ 30 mA

Typical Applications

Low noise MMIC VCO w/Buffer Amplifier for:

• 802.11a, HiperLAN WLAN

• VSAT, UNII & Microwave Radio

• Test Equipment & Industrial Controls

• Military
