EDS-102750 Rev D
Preliminary
Consumer products, such as Set-Top boxes, PVR's, Home
Gateways, and Cable Modems, often require a technique
for "splitting" the incoming RF CATV signal, to perform var-
ious 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 consumption.
This RFIC uses the latest Silicon Germanium
Heterostructure Bipolar Transistor (SiGe HBT) process
featuring 2 micron emitters.
