The MAAM-010399 is an integrated 3 stage
differential amplifier with embedded voltage variable
attenuator. This part is intended as the output
amplifier in a downstream Edge QAM RF modulator.
The module provides excellent linearity and
ACPR at output levels greater than 7 dB above
Cable Labs DRFI requirements. The voltage variable
attenuator (VVA) is implemented with PIN diodes to
provide continuous power level control with high
linearity and is controlled with a single voltage. The
part is packaged in a 5x7 mm PQFN package.
