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.

* Circuit Board Material: Rogers 4350
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 shown is
available from Hittite upon request.
