MACOM launches integrated two-stage differential VGA for DOCSIS 3.0 and 3.1 reverse-path infrastructure equipment

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes analog semiconductors, components and subassemblies for analog, RF, microwave and millimeter-wave applications) has launched an integrated two-stage differential amplifier for DOCSIS 3.0 and 3.1 reverse-path infrastructure equipment.

The MAAM-011186 is designed to provide a highly linear variable gain amplifier (VGA) for network access equipment and head-ends in hybrid fiber coax (HFC) systems. Covering 5-300MHz, the device delivers 22dB of input and output return loss and offers 39dB of gain and 3dB of noise figure with 31.5dB attenuation range, all in a single 7mm RoHS-compliant PQFN package.

The amplifier, with embedded digital step attenuator, delivers 36dB MER (modulation error ratio) performance loaded with 39 channels at 52dBmV per channel. Nominal power dissipation is a low 2.2W in a small 7mm PQFN package, suiting the replacement of legacy discrete solutions in high-density cards and compact system amplifiers. The device can function from either an 8V or 5V voltage supply to provide versatility for system design.

“The MAAM-011186 greatly simplifies reverse-path amplifier design by integrating 39dB of gain with a 6-bit digital step attenuator (DSA) in a single 7mm PQFN package,” says Graham Board, product line manager, Networks and Wired Broadband. “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,” he adds. “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 the MAAM-011186 are available from stock.
