Functional Diagram
General Description
The HMC188MS8 is a miniature frequency doubler
in a plastic 8-lead MSOP package. The suppres-
sion of undesired fundamental and higher order har-
monics is 45 dB typical with respect to input signal
levels. The doubler uses the same diode/balun tech-
nology 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 frequency. The
passive Schottky diode doubler technology contrib-
utes no measurable additive phase noise onto the
multiplied signal.
