Product Description
The RF2105L is a high power, high efficiency linear
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 digital cellular phone transmitters or ISM
applications requiring linear amplification. It is packaged
in a 16-lead ceramic package with a backside ground.
The device is self-contained with the exception of the out-
put matching network and power supply feed line.
