HMC207S8

GaAs MMIC SMT DOUBLE-

BALANCED MIXER, 0.7 - 2.0 GHz

v01.0801

General Description

Features

Functional Diagram

Conversion Loss: 9.0 dB

LO / IF Isolation: 45 dB

LO / RF Isolation: 40 dB

IP3 (Input): +17 dBm

Typical Applications

The HMC207S8 is ideal for:

• Base Stations

• Cable Modems

• Portable Wireless

The HMC207S8 is a miniature double-balanced

mixer in an 8 lead plastic surface mount Small

Outline IC (SOIC) package. This passive MMIC

mixer is constructed of GaAs Schottky diodes and

novel planar transformer baluns on the chip. The

device can be used as an upconverter, down-

converter, biphase modulator (de)modulator, or

phase comparator. The consistent MMIC perfor-

mance will improve system operation and assure

regulatory compliance. The high LO suppression

of 45 to 50 dB yields excellent carrier suppres-

sion for modulator applications.
