Solid State Power Amplifiers for Satellite Communications

We offer a wide range of Solid State Power Amplifiers (SSPAs) in both indoor and outdoor configurations.

Outdoor SSPAs bring high transmit power right to the antenna's feed. Designed for antenna-mount applications, the outdoor SSPAs are entirely self-contained compact and lightweight packages with on board power supply, cooling and monitor and control systems.

Indoor Rack Mount SSPAs achieve the highest power density in the industry along with enhanced maintainability and reliability. Local, front panel control is available with a user friendly interface. Optional Power Supply with N+1 redundancy ensures uninterruptible operation under any circumstances.

Amplifiers for satellite communications, SSPAs are available in C, Ku, X and S bands with power levels ranging from 10 watts up to 1.1 kilowatts readily configurable into 1:1, 1:2, Dual Redundant and Phase Combined Systems. Optional L-band and L-band Fiber Optic Inputs can be provided. Internal block-up-converter allows direct connection of L-band modems to the SSPA for the most cost-effective system designs.

Traveling Wave Tube Amplifiers

We offer an extensive product line of tube-based amplifiers. Highly regarded for their reliable output power and efficiency, Traveling Wave Tube Amplifiers (TWTAs) are used in broadcast and broadband applications throughout the world where customers need to increase power and bandwidth. TWTAs provide high power levels vital to satellite communications applications, both traditional broadcast, the DTH, SNG and flyaway markets, and IP-over-Satellite broadband market.

TWTAs are available in indoor rack-mount and outdoor antenna-mount designs in C, X, Ku, DBS, Ka frequency bands at power levels from 125 watts up to 750 watts. Depending upon user requirements, the amplifiers can be configured for either single thread, redundant or phase-combined system operation. RF gain control, RF filters, cooling, and monitoring and control systems are all self-contained within each amplifier.

All amplifiers for satellite communications meet the most demanding requirements for size, weight, and high reliability. Reduced prime power consumption, lower internal operating temperatures and reliability enhancements are achieved by using the latest dual-stage collector tube technology. Power factor correction circuitry is also included with each TWTA, which minimizes line current distortion and reduces the required Volt-Amps input. These benefits are obtained for both the linear and saturated modes of operation.
