High efficiency E-band MPM for communications applications

L-3 Electron Devices Division (EDD) has developed a compact CW E-band microwave power module (MPM) to cover the 81 to 86 GHz band for communications applications. The power amplifier in the MPM is a periodic permanent magnet focused serpentine waveguide TWT, capable of over 200 W and 50% efficiency. In combination with a predistortion linearizer from LTI, the MPM will provide over 50 W linear power, making it suitable for high data rate communications.
