Functional Diagram
The HMC188MS8 is a miniature frequency doubler
in a plastic 8-lead MSOP package. 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.

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