General Description
the HMC187AMs8(e) is a miniature frequency dou-
bler MMiC in 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 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 pas-
sive schottky diode doubler technology contributes no
measurable additive phase noise onto the multiplied
signal.
