General Description

Features

Functional Diagram

Input IP3: +20 dBm

LO / RF Isolation: 27 dB

Passive: No DC Bias Required

Small Size: 0.88 mm x 1.93 mm

Typical Applications

The HMC294 is ideal for:

• Microwave Point-to-Point Radios

• LMDS

• SATCOM

The HMC294 chip is a miniature passive GaAs

MMIC double-balanced mixer which can be used

as an upconverter or downconverter from 25 - 40

isolations are provided by on-chip baluns, which

require no external components and no DC bias.

All data is measured with the chip in a 50 ohm

test fixture connected via 0.076 mm (3 mil) gold

ribbon of minimal length <0.31 mm (<12 mils).
