The RF2117 is a high power amplifier IC. The device is
manufactured on an advanced Gallium Arsenide Hetero-
junction Bipolar Transistor (HBT) process, and has been
designed for use as the final RF amplifier in analog cellu-
lar phone transmitters between 400MHz and 500MHz or
ISM applications operating at 433MHz. The device is
packaged in a low cost 16-lead plastic package with a
metal backside. The device is self-contained with the
exception of the output matching network and power sup-
ply feed line.
