EDS-102750 Rev E

Preliminary

Consumer products, such as Set-Top boxes, PVR’s, Home Gateways,

and Cable Modems, often require a technique for “splitting” the incom-

ing RF CATV signal, to perform various functions, such as picture-in-

picture, VOIP, data, and video recording.

Sirenza Microdevices’ CGA-0116 is a high performance 3-

output broadband CATV active splitter-amplifier, designed for operation

at 5V. It offers flat gain, high isolation, high IP2, and low power con-

sumption.

This RFIC uses the latest Silicon Germanium

Heterostructure Bipolar Transistor (SiGe HBT) process

featuring 2 micron emitters.

The matte tin finish on Sirenza’s lead-free package utilizes a post

annealing process to mitigate tin whisker formation and is RoHS compli-

ant per EU directive 2002/95. This package is also manufactured with

green molding compounds that contain no antimony trioxide nor haloge-

nated fire retardants.
