Functional Diagram
General Description
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.
