HMC168C8

GaAs MMIC SMT DOUBLE-

BALANCED MIXER, 4.5 - 8 GHz

General Description

Features

Functional Diagram

Conversion Loss: 8.2 dB

LO to RF and IF Isolation: 34 dB

Surface Mount

Small Size, No DC Bias Required

Typical Applications

The HMC168C8 is ideal for:

• Microwave Point-to-Point Radios

• 5.8 GHz ISM Band Circuits

The HMC168C8 is a miniature double-balanced mixer

in a non-hermetic ceramic surface mount package

that can be used as an upconverter, downconverter

or biphase modulator. The device is a passive diode/

balun type mixer with high dynamic range.

Noise

figure is essentially equal to the conversion loss.

The mixer can handle larger signal levels than most

active mixers due to the high third order intercept.

MMIC implementation provides exceptional balance

in the circuit resulting in high LO/RF and LO/IF

isolations and unit-to-unit consistency. This mixer

has applications where small size and surface mount

compatibility are important.
