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 hetero-

junction-bipolar-transistor (HBT) devices

fabricated with InGaP GaAs technology.

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 match-

ing components such as a DC blocking ca-

pacitors on the In/Output pin, a bypass ca-

pacitor and a RF choke for the out port.

All devices are 100% RF/DC tested.
