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.

Features
   Conversion Loss: 15 dB
