General Description
The HMC189MS8 is a miniature passive frequency doubler in a plastic 8-lead MSOP package. The suppression 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 frequency. The passive Schottky diode doubler technology contributes no measurable additive phase noise onto the multiplied signal.

FEATUREs
