The Raytheon RMPA39000 is a high efficiency power amplifier designed for use in point to point radio, point to
multi point communications, LMDS and other millimeter-wave applications. The RMPA39000 is a 3-stage GaAs
MMIC amplifier chip utilizing Raytheon’s advanced 0.15 µm gate length Power PHEMT process and can be used in
conjunction with other driver or power amplifiers to achieve the required total power output.
