Functional Diagram
General Description
The HMC205 is a passive miniature frequency doubler
in a MMIC die. Suppression of undesired fundamen-
tal and higher order harmonics is 32 dB typical with
respect to input signal level. The doubler utilizes the
same GaAs Schottky diode/balun technology found in
Hittite MMIC mixers. It features small size, no DC bias,
and no measurable additive phase noise onto the mul-
tiplied signal.
