Datasheet

Intended for DOCSIS 3.0 and 3.1 reverse path infrastructure equipment, M/A-COM Technology Solutions has introduced the MAAM-011186 integrated two stage differential amplifier. The device delivers gain of 39dB and noise figure of 3dB with 31.5dB attenuation range in a single 7mm RoHS compliant PQFN package.

This integrated two stage differential amplifier with embedded digital step attenuator is designed for customers who require a highly linear variable gain amplifier solution for network access equipment and Head-ends in the hybrid fibre coax system. Operating over a frequency range of 5-300MHz, the MAAM-011186 delivers 22dB of input and output return loss and can function from a 5 or 8V voltage supply.

The MAAM-011186 provides 36dB MER performance loaded with 39 channels at 52dBmV per channel. With low nominal power dissipation of 2.2W in a small package, the device is suited for high density cards and compact system amplifiers, as well as for replacing legacy discrete solutions.

Graham Board, Product Line Manager, Networks and Wired Broadband, M/A-COM Technology Solutions, commented: “The MAAM-011186 greatly simplifies reverse path amplifier design by integrating 39dB of Gain with a 6-bit digital step attenuator in in a single 7mm PQFN package. This part will help to future proof systems by covering existing reverse path bands along with the new high band reverse path for DOCSIS3.1. Combining MACOM’s MMIC expertise with in-house balun solutions, allows us to deliver a truly market leading system solution.”

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