HMC444 Active x8 Multiplier SMT, 9.9 - 11.2 GHz Fout

Product Details

The HMC444LP4(E) is an active miniature x8 frequency multiplier utilizing InGaP GaAs HBT technology in 4x4 mm leadless surface mount package. Power output is +6 dBm typical from a 5V supply voltage and varies little vs. input power, temperature and supply voltage.

Suppression of undesired fundamental and sub-harmonics is >25 dBc typical with respect to output signal level. The low additive SSB phase noise of -136 dBc/Hz at 100 kHz offset helps the user maintain good system noise performance. The HMC444LP4(E) is ideal for use in LO multiplier chains allowing reduced parts count vs. traditional approaches.
