Description  
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.
