Typical Applications
GaAs MMIC HIGH IP3 DOUBLE-
BALANCED MIXER, 0.7 - 1.2 GHz
The HMC351S8 & HMC351S8E are double balanced
mixers in 8 lead plastic surface mount packages.
The passive GaAs schottky diode mixer implements
planar on chip baluns and requires no external com-
ponents. 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 HMC351S8 / HMC351S8E is ideal for:
• Cellular Basestations
• Cable Modems
• Fixed Wireless Access Systems

Evaluation PCB
The circuit board used in the 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 sufficient 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.
