Comtech 750W DBS-Band Antenna Mount High Power Amplifier

The XTD-750DBS series are compact self-contained, antenna mountable power amplifier designed for low cost installation and long life. The design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and the antenna feed horn. RF harmonic filters, cooling, and monitoring & control systems are all self-contained within the HPA. These features provide high reliability, low maintenance costs, and low replacement costs.

The amplifier incorporates a high efficiency multi-stage collector TWT. Some of the benefits are: reduced prime power consumption, lower internal operating temperatures, and reliability enhancement. These benefits are obtained for both the linear and saturated modes of operation.

The units are available with either CW tubes or peak power tubes. CW amplifiers are used when the operator desires maximum transmit power, while peak power HPAs are selected for users that operate only in the linear range. An optional linearizer is available to allow increased transmit power while meeting spectral regrowth requirements.

A complete serial monitoring and control system is built into the unit. The amplifiers may be configured for single thread, redundant or phasecombined operation. It can be configured to control one or two switches.

A remote external controller is available to operate the HPA from user selected location. Mounting brackets can be supplied to mount the HPA to most popular antennas.
