General Description
The HMC187AMS8(E) is a miniature frequency doubler MMIC in plastic 8-lead MSOP package. The suppression of undesired fundamental and higher order
harmonics is 40 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.

The circuit board used in the application should
be generated with proper RF circuit design techniques. Signal lines should have 50 ohm impedance while the package N/C and ground leads
should be connected directly to the ground plane
similar to that shown. The evaluation circuit board
shown is available from Hittite upon request.
