SPOD C-, X-, or Ku-Band Outdoor Amplifier MN-SPODPSX
Introduction Revision 1

1.3 Features
1.3.1 The Solid-State Advantage
The SPOD is constructed with gallium arsenide field-effect transistors (GaAs FETs) to ensure high
reliability. With third-order intermodulation products that are 4 to 6 dB better than TWT ratings,
the CEFD unit replaces TWTs with saturated power levels of up to twice the SPOD’s rated
output. The SPODs also provide mean time between failures (MTBF) that is four to five times
greater than the typical TWT MTBF.
1.3.2 Enhanced Standard Features
The SPOD comes equipped with features that other manufacturers offer only as options.
Included in the base price are temperature compensation, sample ports (on the PS 2 only),
power monitor, power factor corrected supply, and full Ethernet- or serial-based remote
monitor and control (M&C) capabilities.
1.3.3 Built-in Redundancy Controller
The SPOD has the ability to function as a 1:1 (one backup for one primary) redundant controller in
a redundant mode without the use of an external device. The optional redundancy configuration is
implemented by attaching a ganged waveguide/coax transfer switch(es) to the input and output
connectors of the amplifiers, using a combination coaxial cable and waveguide kit.
When the backup SPOD is commanded into redundant mode, it monitors the online SPOD for
faults and status, and automatically maintains a configuration based on the online unit.
A faulted online unit may be disconnected and replaced without affecting the online power
amplifier.
1.3.4 Data Logging Capability
The SPOD includes a built-in data logging capability to enhance system maintainability. By
recording critical operational parameters (e.g., temperature, output power, mute status, etc.) at
time stamped intervals, you can quickly gather intelligence not only about the unit itself, but
also about the unit’s operational environment.
