General Description

The HMC187MS8 is a miniature frequency
doubler in a plastic 8-lead MSOP package.
The suppression of the undesired funda­mental and higher order harmonics is typi­cally 40 to 50 dB with respect to input signal
levels. The doubler uses same diode/balun
structures 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.
