General Description
The HMC157C8 is a miniature frequency
doubler in a non-hermetic ceramic surface
mount package. Suppression of undesired
fundamental and higher order harmonics is
32 to 60 dB with respect to input signal level
and 15 to 43 dB with respect to the desired
output signal level. The doubler uses the
same diode/balun technology used in Hittite
MMIC mixers, features small size and re-
quires no DC bias.
