Description

The MAAM-009879 CATV 2-way active splitter with

the default loop-thru path is a GaAs MMIC which

exhibits low noise figure and distortion in a lead-free

3mm 12-lead PQFN plastic package. The design

features 75 Ω inputs and outputs.

The MAAM-009879 is ideally suited for multi-tuner

set top boxes, home gateways, and other broadband

internet based applications.

The MAAM-009879 is fabricated using M/A-COM

Technology’s E/D pHEMT process to realize default

loop-thru operation, low noise and low distortion.

The process features full passivation for robust

performance and reliability.
