General Description
The HMC204 is a passive miniature frequency dou-
bler in a MMIC die. Suppression of undesired funda-
mental and higher order harmonics is 38 dB typical
with respect to input signal level. The doubler uti-
lizes the same GaAs Schottky diode/balun technol-
ogy found in Hittite MMIC mixers. It features small
size, no DC bias, and no measurable additive phase
noise onto the multiplied signal.
