Ku-Band Solid-State Power Amplifier
Introduction
Each unit has the ability to function as a 1+1 or 1+2 redundancy controller in the backup
mode. The optional redundancy configuration is implemented by attaching a ganged
Waveguide/coax transfer switch (es) to input and output connectors of the amplifiers with
a combination coaxial cable and Waveguide kit.
When the backup KPA is commanded into the controller mode, it monitors the online
KPA's for faults. A faulted online unit may be disconnected and replaced without
affecting the online power amplifier.
