Typical Applications
The HMC189MS8 is suitable for:
Wireless Local Loop
LMDS, VSAT, and Pt to Pt Radios
UNII & HiperLAN
Test Equipment
The HMC189MS8 is a miniature passive frequency
doubler in a plastic 8-lead MSOP package. The sup-
pression of undesired fundamental and higher order
harmonics is 33 dB typical with respect to input
signal levels. The doubler uses the same diode/
balun technology used in Hittite MMIC mixers. The
doubler is ideal for high volume applications where
frequency doubling of a lower frequency is more
economical than directly generating a higher fre-
quency. The passive Schottky diode doubler tech-
nology contributes no measurable additive phase
noise onto the multiplied signal.

The circuit board used in the fi nal application should be generated with proper RF circuit design techniques. Signal
lines at the RF port should have 50 ohm impedance and the package ground leads should be connected directly to the
ground plane similar to that shown above. The evaluation circuit board shown above is available from Hittite Microwave
Corporation upon request.
