Product Descrip on
BeRex’s BT301 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‐
junc on‐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 consump on current
(350mA) 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.
