General Description

The HMC158C8 is a miniature frequency
doubler MMIC in a non-hermetic ceramic
surface mount non-hermetic package. Sup­pression of undesired fundamental and
higher order harmonics is 34 to 58 dB with
respect to input signal level and 19 to 45 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. Applications include Telecom radios

5.2 GHz UNII and 5.8 GHz ISM Band cir­cuits.

Guaranteed Perf ormance, 50 Ohm system -55 to +85 deg C
