Premier Supplier of High Power Amplifiers for Satellite Communications
 

Comtech Xicom Technology has grown to become a leading supplier of satellite communications amplifiers (satcom), offering the broadest product line in the industry. Our focus on customers, innovation and quality spurred growth and created a company with a reputation for excellence. Regarded as the industry leader in general, Xicom provides robust, highly efficient and reliable traveling wave tube amplifiers (TWTAs), Klystron power amplifiers (KPAs), solid state power amplifiers (SSPAs) and upstream block converters ( BUCs) for commercial and military broadcast and broadband applications worldwide. These Xicom High Power Amplifiers (HPAs) are in use on critical communication links on the ground, in the air and at sea; they support traditional and direct home broadcasting, mobile news collection, transportable and flyaway systems.

TWTA's Antenna Mount

Xicom TWTAs are known worldwide for their reliable operation and long service life. By decreasing the need for longwave guides, transmission power is optimized and RF losses are reduced. Acclaimed for their compact and highly efficient design, Xicom antenna mounting amplifiers dramatically reduce installation and operating costs.

 

TWTA's Superpower

Comtech Xicom Technology is developing a line of high power TWT amplifiers.

 

TWTA's Touchscreem

Xicom Technology offers the world's largest selection of rack mount TWTA. Xicom rack mounted TWTAs are known worldwide for their superior technology and reliability. Our TWTA will meet your most demanding size, weight, efficiency and reliability requirements. They are the ideal choice for fixed, SNG and flyaway applications. Xicom's new LCD LCD screen control front panel offers an easy-to-use interface for monitoring and controlling the amplifier. The new touchscreen front panel displays HPA operational status, including power and temperature output, graphical parameter trend analysis displays, and event logs. Local and remote diagnostics can also be easily performed via an Ethernet interface. This new screen eliminates the need for separate external controllers for common architectures. Another valuable feature is that all operational data is saved to the amplifier's nonvolatile memory, providing a complete HPA history in case the unit needs service or repair.

AC POWERED OUTDOOR SSPA

 

Bobcat DC BUCs

Designed for compact handheld terminals that need high power from very small packages operating in challenging environments, Bobcat are high performance external BUCs, powered by DC and mounted on power with large resources, including extensive data logging, web-based GUI easy to use SNMP Ethernet (v1 or v3) and interchangeability between the X, Ku and Ka bands. From the 4.5 pound Bobcat 64Ku onwards, these BUCs provide high linear power density for the most demanding satcom terminal applications. These BUCs are:

  • We are a family owned and operated business.

  • Small, lightweight 4 lb to 10 lb power assembly packages

  • Powerful linear power from 16 W to 50 W per MIL-STD-188-164

  • Low energy efficient consumption, optional battery saving and key line modes

  • Rugged environment from -40C to + 60C, MIL-STD-810 environment

  • X, Ku- and Ka band flexible interchangeable bobcats Options for various Ka and SNMP v3 bands

 

The new product line includes the Bobcat 50X (25 watt linear X band); the Bobcat 64Ku (32 watt linear Ku band); and the Bobcat 32Ka (16 watt Ka band linear BUC), each about 110 inches. and weighing 4 to 5 pounds. Even in this small package, you don't have to give up on features. The 5 pound Bobcats still have extensive control of attenuation and calibration capabilities, data logging and availability of the Web GUI and security features, such as the optional implementation of SNMP v3.

 

If you want the most capable little BUC on the market - you need a Bobcat!

 
 

Falcon Airbone SSPAs

Designed for in-air satcom systems that need high energy density and high efficiency, Falcons are high performance, external cabin cab SSPAs / BUCs, designed and certified to DO-160 and MIL-STD-810 requirements. These Falcon SSPAs with internal L-band BUCs provide extensive data logging, very high reliability, attenuation control and full calibration capability. Available in the Ku band and the Ka band, Falcon SSPAs offer high performance and high linear power density for demanding airborne satcom applications. These SSPAs are:

  • Powerful linear power from 20W to 50W

  • Light weight from 14 lb to 20 lb

  • Compact ARINC package

  • Trusted certificate for DO-160 Category A1 to F2

  • Flexible options for multiple switched Ka and BUC bands, extensive attenuation control and calibration capability

 

The new Falcon product line includes the Falcon 100Ku (50W linear Ku band), Falcon 40Ka (20W linear Ka band) and 50Ka (25W linear Ka band), each in an ARINC package weighing less than 20 pounds . Xicom designs Falcon SSPAs to support DO-160 compliant requirements from category A1 to F2. The high-efficiency technology and advanced packaging techniques used enable industry-leading products to meet the tough environments of aerial applications. These powerful Falcon SSPAs are offered with a variety of single-band and multi-band BUC options in the 27.5 to 31.0 GHz Ka band. They also incorporate extensive attenuation control, data logging and availability of the Web GUI and are executed with a frequency reference of 50 MHz.

If you need a powerful and reliable SSPA or BUC to make your satcom satellite terminal fly - you need a Falcon!

 

Systems

For amplifier redundancy switching, the redundancy function can be located on the amplifiers or on a separate controller. Amplifiers can accommodate simple systems, while separate controllers are required for more complex systems. Regardless of where the redundancy or switching decision is made, the decision depends on the status of the amplifiers. All Xicom systems rely on hardware-summarized fault signals for amplifier status, that is, fault relay rescued contacts as it provides the most robust and fast way to auto-switch. Additional monitor and amplifier control are communicated between amplifiers and controllers, if necessary, via serial or Ethernet communications.

Controllers

Comtech Xicom amplifiers are complemented by control system solutions available in the combined 1: 1, 1: N and variable phase configurations.

Comtech Xicom offers a touchscreen control interface for external amplifiers. The LCD touch screen provides an easy-to-use interface for monitoring and controlling SATCOM power amplifiers in a standard 19-inch rack-width configuration. The new touchscreen front panel displays HPA operating status, including power and temperature output, graphical parameter trend analysis displays, and event logs. Local and remote diagnostics can also be easily performed via an Ethernet interface. This new screen eliminates the need for separate external controllers for common architectures because it can show and control waveguide switches and a combiner for cost and space savings. Another valuable feature is that all operating data is saved within the amplifier's nonvolatile memory, providing a complete HPA history in case the unit needs service or repair.
