Description

The RF2131 is a high-power, high-efficiency amplifier IC.

RF2131 is manufactured on an advanced Gallium Ars-enide Heterojunction Bipolar Transistor (HBT) process,and RF2131 has been designed for use as the final RF amplifier inAMPS and ETACS handheld equipment, spread spec-trum systems, CDPD, and other applications in the800MHz to 950MHz band. On-board power control pro-vides over 30dB of control range with an analog voltageinput, and provides power down with a logic "low" forstandby operation. Although it is intended for class Coperation, linear class AB operation can be achieved byraising the bias level. RF2131 is self-contained with50Ω input and the output can be easily matched to obtainoptimum power and efficiency characteristics.
