Product Description
The RF2115L 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 or ISM applications operating at
915MHz. The device is packaged in a 16-lead ceramic
quad leadless chip carrier with a backside ground. The
device is self-contained with the exception of the output
matching network and power supply feed line. A two-bit
digital control provides 4 levels of power control, in 10dB
steps.
