Typical Applications
The HMC218MS8 is ideal for:
UNII & HiperLAN
Portable Wireless
PCMCIA
The HMC218MS8 is an ultra miniature double-
balanced mixer in an 8 lead plastic surface mount
package (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,
bi-phase (de)modulator, or phase comparator.
The consistent MMIC performance will improve
system operation and assure regulatory compli-
ance.

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.
