HMC351S8

GaAs MMIC HIGH IP3 DOUBLE-

BALANCED MIXER, 0.7 - 1.2 GHz

Features

Conversion Loss: 9.0 dB

LO/IF Isolation: 35 dB

LO/RF Isolation: 42 dB

Input IP3: +25 dBm

Input IP2: +48 dBm

General Description

The HMC351S8 is a double balanced mixer in an
8 lead plastic surface mount package. The passive
GaAs schottky diode mixer implements planar on
chip baluns and requires no external components.
The mixer can be used as an upconverter, down
converter, or modulator. The mixer provides 9 dB
conversion loss and +25 dBm IIP3 with LO drive
levels of +19 dBm. The design was optimized for
low cost high volume applications where high con­verter linearity is required. The high LO suppres­sion of 42 dB yields excellent carrier suppression for
modulator applications.

The circuit board used in the fi nal application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads should be connected directly to the ground
plane similar to that shown. A suffi cient number of via
holes should be used to connect the top and bottom
ground planes. The evaluation circuit board as shown
is available from Hittite upon request.
