Description
The MAAM-011186 is an integrated 2 stage
differential amplifier with embedded digital step
attenuator (DSA) assembled in a lead-free 7 mm
48-lead PQFN package.
This amplifier 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. This device is
optimized for high output power and low current from
8 V bias but can also be operated from 5 V bias with
flexibility to adjust DC current with external
components. The module provides a power down
function for each of the amplifier stages.
This amplifier is ideally suited for use in CATV
reverse path applications.
