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.
