HMC265LM3

GaAs MMIC SUB-HARMONIC

SMT MIXER, 20 - 31 GHz

v01.1201

General Description

Features

Functional Diagram

The HMC265LM3 is a 20 - 31 GHz surface mount

sub-harmonically pumped (x2) MMIC mixer down-

converter with integrated LO and IF amplifiers in

a SMT leadless chip carrier package. The 2LO to

RF and IF isolations are an excellent 28 to 47 dB,

eliminating the need for additional filtering. The LO

amplifier is a single bias (+3V to +4V) two stage

design with only -4 dBm drive requirement. All data is

with the non-hermetic, epoxy sealed LM3 packaged

device mounted in a 50 ohm test fixture. Utilizing the

HMC265LM3 eliminates the need for wirebonding,

thereby providing a consistent connection interface

for the customer.

Integrated LO Amplifier: -4 dBm Input

Sub-Harmonically Pumped (x2) LO

High 2LO/RF Isolation: > 28 dB

LM3 SMT Package

Typical Applications

The HMC265LM3 is ideal for:

• 20 and 31 GHz Microwave Radios

• Downconverter for Point to Point Radios

• LMDS and SATCOM
