MAAM-010399

Differential Variable Gain Amplifier

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.
