Differential CATV Variable Gain Amplifier

By MacomTechnology Solutions 117

Differential CATV Variable Gain Amplifier

The MAAM-011186 from MACOM is designed for customers who need a low noise, high powered, and extremely linear variable gain amplifier (VGA) solution for CATV reverse-path applications. This integrated two-stage differential amplifier is embedded with a digital step attenuator that is assembled in a lead-free 7 mm 48-lead PQFN package. Unlike the competing variable gain amplifiers, the MAAM-011186 can function at a 5 V bias to provide flexibility and versatility for high-performance applications. The MAAM-011186 provides greater than 36 dB MER in output power for 64 QAM modulation with 39 channels at 52 dBmV per channel 39 dB gain. These features enable this VGA to be optimized for power and linearity.
