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-con-
tained with the exception of the output matching network
and power supply feed line. A two-bit digital control pro-
vides 4 levels of power control, in 8dB steps.
