HMC430LP4

MMIC VCO w/ BUFFER

AMPLIFIER, 5.0 - 5.5 GHz

v02.0604

General Description

Features

Functional Diagram

The HMC430LP4 is a GaAs InGaP Heterojunction

Bipolar

Transistor

(HBT)

MMIC

VCO

with

integrated resonator, negative resistance device,

varactor diode, and buffer amplifier. The VCO’s

phase noise performance is excellent over

temperature, shock, vibration and process due to

the oscillator’s monolithic structure. Power output

is 2 dBm typical from a 3.0V supply voltage. The

voltage controlled oscillator is packaged in a

low cost leadless QFN 4 x 4 mm surface mount

package.

Pout: +2 dBm

Phase Noise: -103 dBc/Hz @100 kHz

No External Resonator Needed

Single Supply: 3V @ 27 mA

Typical Applications

Low noise MMIC VCO w/Buffer Amplifier

for C-Band applications such as:

• 802.11a & HiperLAN WLAN

• VSAT Radios

• UNII & Pt to Pt Radios
