Product Detail

MAAM-011122
Differential CATV Variable Gain Amplifier
The MAAM-011122 is an integrated 2 stage differential amplifier with embedded digital step attenuator (DSA). This part is intended for CATV Reverse Path applications. The module provides excellent linearity and high output power with greater than 30 dB MER for 64 QAM modulation with 39 channels and 52 dBmV per channel. Gain in the minimum attenuation state is typically 39 dB. The internal DSA offers 31.5 dB attenuation range with 0.5 dB steps. The module also provides power down function for each of the amplifier stages. The part is packaged in a lead-free 7 mm PQFN package.
