Description
The MAAM-011168 is an integrated 2 stage
differential amplifier with embedded digital step
attenuator (DSA) assembled in a lead-free 7 mm
48-lead PQFN package.
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 40 dB. The internal DSA offers 15.5 dB
attenuation range with 0.5 dB steps. The device is
optimized for high output power with 8 V bias and
can also operate from 5 V bias if lower DC power
consumption and output level is desired. The
module also provides a power down function for
each of the amplifier stages.
This amplifier is ideally suited for use in CATV
reverse path applications.

3. All pins not listed in the table are “No Connection” and should
be left unconnected.
4. The exposed pad centered on the package bottom must be
connected to RF and DC ground.
5. MACOM recommends grounding pin 40. It is connected to the
CMOS controller but does not affect attenuator setting.
