Stage 2 Input (+)

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.
