Comtech XTD-400C-B1 400 Watt C-Band Antenna Mount Amplifiers With Block Upconverter

The XTD-400-B1 is a series of compact self contained antenna mountable power amplifiers with a built-in block upconverter designed for low cost installation and long life.

The XTD-400-B1 design eliminates the need for an amplifier shelter as well as a long waveguide run between the amplifier and the antenna feed horn. For example, an antenna mount 400 Watt Ku-Band amplifier with its shorter waveguide run will often deliver EIRP comparable to a 600 Watt rack mount HPA. RF 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 XTD-400-B1 uses high efficiency dual-stage collector Traveling Wave Tubes (TWT). Some benefits of this type of TWT 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 unit incorporates an L-Band block Upconverter, thereby eliminating the need for a separate outdoor unit (ODU). The L-Band transmit signal and a 10 MHz reference signal are brought out to the unit on a single coax line.

The XTD-400-B1 may be configured for single thread, redundant, phase-combined, to linearized operation. A remote external controller is available to operate the HPA from a user selected locations. Mounting brackets can be supplied to mount the HPA to most popular antennas.
