HMC204
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 fundamental 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.
