INPUT DRIVE LEVEL :10 to 20 dBm
General Description
The HMC157 is a miniature frequency doubler in a MMIC die. Suppression of undesired fundamental and higher order harmonics is 35 to 60 dB with respect to input signal
level and 18 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.
