M/A-COM Technology Solutions Holdings Inc. (MACOM) has unveiled an integrated two stage differential amplifier for DOCSIS 3.0 and 3.1 reverse path infrastructure equipment. According to the company, the MAAM-011186 is geared for customers who require a highly linear variable gain amplifier (VGA) solution for network access equipment and head-ends in the hybrid fibre coax (HFC) system.

This device offers 39dB of gain and 3dB of noise figure with 31.5dB attenuation range all delivered in a single 7mm RoHS compliant PQFN package.

The MAAM-011186 is an integrated two stage differential amplifier with embedded digital step attenuator. The amplifier delivers 36dB MER performance loaded with 39 channels at 52dBmV per channel. Nominal power dissipation is a low 2.2W in a small 7mm PQFN package making this an ideal solution for high density cards and compact system amplifiers. The MAAM-011186 is an ideal solution to replace legacy discrete solutions.

Covering 5-300MHz, this device delivers 22dB of input and output return loss. The device can function off either an 8V or 5V voltage supply to provide the ultimate versatility to the system designer.

Production quantities and samples of MAAM-011186 are available from stock.
