General Description
The HMC331 is a passive miniature frequency dou-
bler MMIC. Suppression of undesired fundamental
and higher order harmonics is 50 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,
requires no DC bias, and adds no measurable addi-
tive phase noise onto the multiplied signal.
