SPOD High Power Outdoor SSPA Series Amplifier Systems

Comtech EF Data’s (CEFD) Series of High-Power Outdoor SPOD C-, X-, and Ku-Band Solid-State Power Amplifiers (SSPA) provide a cost-effective, more reliable replacement for TWT amplifiers in satellite communications terminals. The SPOD delivers its rated power at the 1 dB compression point, to the transmit waveguide flange.

The Solid State Advantage

Each SPOD SSPA is constructed with highly reliable GaAs FETs. With third order intermodulation products from 4 to 6 dB better than TWT ratings, the CEFD unit has the ability to replace TWTs with saturated power levels of up to twice the SPOD’s rated output.

Functional Description

A SPOD consists of an SSPA module with the Monitor/Control Processor (MCP), an integrated power supply, and a field replaceable fan assembly. The amplifier features a Comtech EF Data low loss combining technique and MCP-based temperature versus gain compensation.

Feature Packed

The SPOD SSPAs are equipped with useful features that other manufacturers offer as options. Included in each unit’s base price are temperature compensation, sample ports, power monitor, power factor corrected supply and full remote monitor and control capabilities, including Ethernet HTTP pages and SNMP.

Redundancy

Another challenge addressed by the SPOD topology is the increasing need for redundant RF solutions. With a unique solution to system control, The SPOD offers a very cost-effective solution for 1:1 redundant TX requirements.

Integrated Power Supply

All SPOD SSPAs have a self-contained, extremely rugged, power supply. While generally fielded as an AC powered unit, SPODs are also available with -48 VDC power supplies.

Data Logging Capability

To greatly enhance system maintainability, the SPOD line includes a built in data logging capability. By recording critical operational parameters (such as temperature, output power, mute status, etc.) at time stamped intervals, the user can quickly gather intelligence not only about the unit itself, but also the unit’s operational environment.
