HMC157C8 MICROWAVE CORPORATION GaAs MMIC SMT FREQUENCY DOUBLER 1 - 2 GHz INPUT V01.0700 FEBRUARY 2001 Features 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 requires no DC bias.
