GaAs MMIC PASSIVE FREQUENCY
DOUBLER, 4 - 8 GHz INPUT
Features
Conversion Loss: 17 dB
Fo, 3Fo, 4Fo Isolation: 38 dB
Passive: No Bias Required
General Description
The HMC204 is a passive miniature frequency
doubler in a MMIC die. Suppression of undesired fun-
damental and higher order harmonics is 38 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 multiplied signal.
