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.
