700-2700 MHz 1.5~2.0W Power Amplifier

BT331

BeRex’s BT331 is a high power and a high

dynamic range amplifier in a low cost sur-

face mount package(SOIC-8) with a RoHS-

compliant, that incorporates reliable het-

erojunction-bipolar-transistor (HBT) de-

vices fabricated with InGaP GaAs technol-

ogy.

This device is designed for use where high

linearity is required and features high OIP3

and Power with low consumption current

(400mA) and requires a few external

matching components such as a DC block-

ing capacitors on the In/Output pin, a by-

pass capacitor and a RF choke for the out

port.
