General Description
The HMC188MS8 & HMC188MS8E are miniature
frequency doublers in plastic 8-lead MSOP packages.
The suppression of undesired fundamental and higher
order harmonics is 45 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 frequency. The passive
Schottky diode doubler technology contributes no
measurable additive phase noise onto the multiplied
signal.
