HMC204C8
GaAs MMIC SMT PASSIVE FREQUENCY
DOUBLER, 4 - 8 GHz INPUT
Features
Conversion Loss: 16 dB
Fo, 3Fo, 4Fo Isolation: 40 dB
Passive: No Bias Required
General Description
The HMC204C8 is a passive miniature frequency
doubler in a non-hermetic surface mount package.
Suppression of undesired fundamental and higher
order harmonics is 40 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.
