General Description
The HMC444LP4 & HMC444LP4E are active miniature x8 frequency multipliers utilizing InGaP GaAs HBT technology in 4x4 mm leadless surface mount packages. 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 & HMC444LP4E are ideal for use in LO multiplier chain...
