Functional Diagram
General Description
The HMC187MS8 & HMC187MS8E are miniature fre-
quency doubler MMICs in plastic 8-lead MSOP pack-
ages. The suppression 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 eco-
nomical than directly generating a higher frequency.
The passive Schottky diode doubler technology con-
tributes no measurable additive phase noise onto the
multiplied signal.

The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines should have 50 ohm imped-
ance while the package ground leads and exposed
paddle should be connected directly to the ground
plane similar to that shown. The evaluation circuit
board shown is available from Hittite upon request.
