General Description
The HMC1105 is a passive miniature frequency doubler in a MMIC die. Suppression of undesired fundamental and higher order harmonics is up to 41 dB typical with respect to input signal level. The doubler utilizes the same GaAs Schottky diode/balun technology found in Hittite MMIC mixers. The HMC1105 features small size, requires no DC bias, and adds no measurable additive phase noise onto the multiplied signal. The HMC1105 is compatible with conventional die attach methods which make it ideal for MCM and hybrid microcircuit applications. All data shown herein is measured with the chip in a 50 ohm environment and contacted with RF probes.
