MACOM Highly Linear Variable Gain Amplifier
M/A-COM Technology Solutions (MACOM)  (Cologne, Germany) has introduced a highly linear two stage differential amplifier for DOCSIS3.1 reverse path infrastructure applications at the ANGACOM 2013 Exhibition and Congress. The MAAM-011122 is an integrated two stage differential variable gain amplifier designed specifically for CATV head-end, and system amplifier infrastructure reverse path applications. This multi-chip module VGA leverages leading edge technologies providing best in class linearity and high output power. This enables customers to achieve 36dB MER for 64 QAM modulation with 39 channels at 52 dBmV per channel. Unlike the competition, this device offers a power down function for each of the amplifier stages allowing reduced power consumption (green operation), when less gain is required. This configurability makes the MAAM-011122 an ideal solution to replace legacy Silicon and GaAs solutions for upcoming DOCSIS3.1 upgrades. Features include:
- 5 – 300 MHz frequency range.
- Strong performance with 3 dB low Noise Figure and 39 dB Gain.
- 7mm 48-Lead PQFN package.
- Low harmonics with differential input and output control.
