HMC329

GaAs MMIC DOUBLE-BALANCED

MIXER, 25 - 40 GHz

v04.1007

General Description

Features

Functional Diagram

Passive: No DC Bias Required

Input IP3: +19 dBm

LO/RF Isolation: 42 dB

Small Size: 0.85 x 0.55 x 0.1 mm

Typical Applications

The HMC329 is ideal for:

• LMDS

• Microwave Point-to-Point Radios

• SATCOM

* Unless otherwise noted, all measurements performed as downconverter, IF= 1 GHz.

The HMC329 chip is a miniature passive double

balanced mixer which can be used as an upconverter

or downconverter from 25-40 GHz in a small chip

area of 0.85 x 0.55 mm. Excellent isolations are

provided by on-chip baluns, and the chip requires no

external components and no DC bias. Measurements

were made with the chip mounted and ribbon bonded

into in a 50-ohm microstrip test fixture that contains

5-mil alumina substrates between the chip and

K-connectors. Measured data includes the parasitic

effects of the assembly. RF connections to the chip

were made with 0.076 mm (3-mil) ribbon bond with

minimal length <0.31mm (<12 mil).
