| The Xicom XTD-400DBL series are compact selfcontained antenna mountable power amplifiers designed for low cost installation and long life. |
|
The XTD-400DBL series 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 mounted 350 Watt amplifier with its shorter waveguide run will often deliver EIRP comparable to a 600 Watt rack mounted HPA. RF filters, cooling, and monitoring & control systems are all selfcontained within the HPA. These features provide high reliability, low maintenance costs, and low replacement costs.
The XTD-400DBL series incorporates high efficiency, dualstage collector TWTs. Some of the 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. One of the features of the XTD-400DBL series is incorporation of power factor correction circuitry that minimizes line current distortion and reduces the required voltamps. The combination of power factor correction and high efficiency TWTs reduces input VoltAmps by 45% when compared to equivalent amplifiers. A high frequency resonant conversion power supply is used that accepts a wide range of prime power (100 to 260 VAC). The automatic features of the power supply include quick recovery from prime power outages and multiple helix fault resets (three fault cycles).
A complete monitoring & control system is built into the unit. Ten status and fault monitors are provided for external monitoring.
The XTD-400DBL series can 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.

The CDM-750 accommodates the most demanding Internet Service Provider (ISP) and telco backhaul links by offering users the most advanced combination of space segment saving capabilities while minimizing the need for unnecessary overhead. With the ability to process packets at line speed, the CDM-750 will not throttle throughput due to processing limitations.
Beginning with the most efficient coding and modulation available, the CDM-750 leverages the DVB-S2 EN 302 307 LDPC/BCH standard to provide the best possible combination of coding and foreword error correction ensuring that the maximum amount of satellite traffic is transported for a given signal to noise capacity.
Implementing Adaptive Coding and Modulation (ACM) operation (in packet-based applications) allows link margin to be converted to user capacity during non-faded conditions by taking advantage of the actual signal to noise ratio rather than calculated worst case signal to noise. This technology transforms link margin, implementation margin and margin for antenna pointing directly to improved throughput.
By using the best encapsulation methods, the CDM-750 further increases throughput by using minimal overhead. In G.703 synchronous mode, users can implement monitor and control over the satellite with no additional overhead. When using Ethernet bridge mode, less than 1% overhead is used for encapsulation.
Additionally, the CDM-750 leverages Comtech EF Data’s powerful DoubleTalk® Carrier-in-Carrier® “Adaptive Cancellation” technology. With the ability to overlay TX and RX carriers, Carrier-in-Carrier enables the operator to establish the perfect balance between bandwidth and power, enabling the best possible use of the satellite resource and reducing operating expenses (OPEX).
These technologies alone offer enormous savings to the ISP and telco operator. When used in combination, however, the savings are astronomical.
The innovative high-performance architecture of the CDM-750 allows efficient networking and transport over satellite links while supporting a wide range of applications and network topologies.

The unit features a menu driven front panel display, RS-232/422/485 serial port and Ethernet interfaces for complete computer control. Forward power, reverse power and temperature, and default parameters are easily monitored on the four line front panel display.
Gain control is provided via the front panel or through the remote interfaces.
A high frequency resonant conversion power supply is used that accepts a wide range of prime power (90 to 264 VAC). Power factor correction circuitry is also included which minimizes line current distortion and reduces the required Volt- Amps input.
The amplifier includes an integrated L-Band Block Upconverter that interfaces to standard modems operating in the 950-1450 MHz range. The L-Band transmit signal and 10 MHz reference are brought to the unit over a single coaxial line.
Depending upon user requirements, this high power amplifier can be configured for single thread, redundant, or phase combined configurations.

The L-Band input interfaces to standard modems operating in the 950 – 1450 MHz range.
Intended for outdoor operation, the XTS-40X-B1 eliminates the need for a separate shelter. The construction and light weight allows for direct mount to the antenna. This eliminates long waveguide runs and associated RF losses.
Forced air cooling is implemented in the package to allow reliable operation over extended temperature ranges. The monitor and control (M&C) interface provides a component system status.
The block upconverter operates from an external, weatherized power supply which provides the system DC sources.
The L-Band transmit signal and 10 MHz reference frequency are brought to the unit over a single coaxial line.
