GaAs MMIC MIXER w/ INTEGRATED

IF & LO AMPLIFIER, 1.8 - 3.9 GHz

v01.0508

General Description

Features

Functional Diagram

The HMC622LP4E is a highly integrated converter

IC that operates from 1.8 to 3.9 GHz for both up-

conversion and downconversion applications. The

HMC622LP4E incorporates a high dynamic range,

double-balanced mixer core with integrated LO and

IF amplifiers, making it ideal for compact transceiver

applications in GSM, WCDMA, TD-SCDMA, WiBro

and WiMAX. This versatile converter RFIC operates

with a low LO input power level of only +3 dBm, pro-

vides up to 10 dB conversion gain, and exhibits +23

dBm Input IP3 in downconversion mode. This RFIC

provides up to 12 dB conversion gain in upconverter

mode.

Specific evaluation boards are available for

both upconversion and downconversion modes.

High Input IP3: +23 dBm

Low Input LO Drive: 0 to +6 dBm

High LO to RF Isolation: 33 dB

High Conversion Gain: 9 dB

Can be used for upconversion or downconversion

Typical Applications

The HMC622LP4 / HMC622LP4E is ideal for:

• PCS / 3G Infrastructure

• Base Stations & Repeaters

• WiMAX & WiBro

• Broadband & Fixed Wireless
