provides a cost effective and more reliable replacement for Transfer Wave Tube (TWT) amplifiers in Ku-Band terminals.
The Comtech KPA provides a cost effective and more reliable replacement for Transfer Wave Tube (TWT) amplifiers in Ku-Band terminals. Due to its small form factor, it is also ideal for the construction of small "flyaway" terminals, medium size (equivalent to Intelsat F) earth stations, and hub earth stations for small to medium size private networks, or point-to-point links.The Solid-State Advantage
Each KPA series SSPA is constructed with highly reliable Gallium Arsenide Field Effect Transistors (GaAs FETs). With third order inter-modulation products from 4 to 6 dB better than TWT ratings, the Comtech EF Data unit replaces TWTs with saturated power levels of up to twice the KPA's rated output. The KPA SSPSs also provide a Mean Time Between Failure (MTBF) that is 4 to 5 times greater than the typical TWT MTBFs.Option Free
Comtech EF Data's KPA series of SSPAs come equipped with useful features that other manufacturers offer as options. Included in the base price are temperature compensation, sample ports, power monitor, rack slides, and full remote monitor and control capabilities.Functional Description
Each KPA series SSPA consists of a Comtech EF Data SSPA module with the Monitor/Control Processor (MCP), a field replaceable 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.Field Replaceable Power Supply
Recognizing that the MTBF limiting factor for almost all electronic equipment is the power supply, the KPA provides for easy field replacement. Simply disconnect the AC mains, release the clasps, and remove the supply from the SSPA module.Built-in Redundancy Controller
