RFPA3805SQ Overview

GaAs HBT 2-Stage Power Amplifier 700MHz to 2700MHz

RFPA3805
GaAs HBT 2-Stage Power Amplifier
700MHz to 2700MHz
RFMD’s RFPA3805 is a GaAs HBT linear power amplifier
specifically designed for Wireless Infrastructure applications.
Using a highly reliable GaAs HBT fabrication process, this high
performance two-stage amplifier achieves high linearity over a
broad frequency range. Its external matching allows for use
across various radio platforms within 700MHz to 2700MHz. The
RFPA3805 can also be optimized for high-efficiency applications.
