Product Description
The RF2155 is a 3V medium power programmable gain amplifier IC. The
device is manufactured on an advanced Gallium Arsenide Heterojunction
Bipolar Transistor (HBT) process, and has been designed for use as the
final RF amplifier in analog cellular phone transmitters or ISM applications
operating at 915MHz. 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 8dB steps.
