Functional Diagram
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.

The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines should have 50 ohm imped-
ance 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.
