Preliminary
Product Description
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 various functions, such as picture-inpicture, VOIP, data, and video recording. Sirenza Microdevices' CGA-0116 is a high performance 3output 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. The matte tin finish on Sirenza's lead-free package utilizes a post annealing process to mitigate tin whisker formation and is RoHS compliant per EU directive 2002/95. This package is also manufactured with green molding compounds that contain no antimony trioxide nor halogenated fire retardants.

This pin should be bypassed to ground for max gain Connection to ground. Voltage supply connection for input. This pin should be bypassed with a suitable capacitor. Bias connection for input. This pin should be bypassed with a suitable capacitor RF input pin. This pin requires a DC blocking capacitor Input bias resistor connection for setting bias current. This pin should be connected to groung for specified operation. Gain adjust for Output 3. This pin should be bypassed to ground for max gain RF Output 1 and DC supply pin. This pin required the use of an external blocking capacitor and RF choke. RF Output 2 and DC supply pin. This pin required the use of an external blocking capacitor and RF choke. Gain adjust for Output 3. This pin should be bypassed to ground for max gain RF Output 3 and DC supply pin. This pin required the use of an external blocking capacitor and RF choke. The exposed backside paddle needs to be well grounded with multiple vias. This is the main electrical GND and the main thermal path.
