Comtech 1250W Ku-Band Antenna Mount High Power Amplifier
- 1250 watts peak power, 575 watts linear power with linearizer;
- Rugged design operates to +60ºC;
- Optional L-band BUC;
- No shelter required;
- Identical outline makes an ideal upgrade from 750W systems;
- Includes overdrive protection circuitry.
The XTD-1250KHE is a compact, self-contained, antenna mountable power amplifier designed for low cost installation and long life. The XTD-1250KHE design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and antenna feed horn. RF filters, cooling, and monitoring & control (M&C) systems are all self-contained.
The XTD-1250KHE incorporates high efficiency, multi-stage collector 1250W peak power TWT. The output operational power is limited, however the linear power performance at 575W and below is equivalent to a 1250W tube. Depending upon user requirements, the amplifier can be configured for either single thread or redundant system operation.
The XTD-1250KHE may be configured for single thread, redundant, phase-combined, or linearized operation.
A remote external controller is available to operate the HPA from a user selected location. Mounting brackets can be supplied to mount the HPA to most popular antennas.
