MAAM-011194
75 Ohm Differential Variable Gain CATV Amplifier
The MAAM-011194 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 to support DOCSIS3.1 applications. The module provides high gain, low noise figure and excellent linearity and ACPR at output levels 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 with a single control voltage. The part is packaged in a 5 x 7 mm PQFN package.
