General Description
Features
Functional Diagram
Ultra Small Package: MSOP8
Conversion Loss: 9 dB
LO / RF Isolation: 24 dB
Input IP3: +17 dBm
Electrical Specications, TA = +25° C, As a Function of LO Drive
Typical Applications
The HMC208AMS8 / HMC208AMS8E is ideal for:
• Base Stations
• PCMCIA Transceivers
• Cable Modems
• Portable Wireless
The HMC208AMS8 & HMC208AMS8E are ultra min-
iature double-balanced mixers in 8 lead plastic surface
mount packages (MSOP). 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, downconverter, biphase
(de)modulator, or phase comparator. The consistent
MMIC performance will improve system operation and
assure regulatory compliance.

The circuit board used in the 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
shown is available from Hittite upon request.
