Typical Applications
The HMC187MS8 is suitable for:
Wireless Local Loop
LMDS, VSAT, and Pt to Pt Radios
UNII & HiperLAN
Test Equipment
The HMC187MS8 is a miniature frequency doubler
MMIC in a plastic 8-lead MSOP package. The sup-
pression of undesired fundamental and higher order
harmonics is 40 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 should have
50 ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
