POWER AMPLIFIER MODULES

We design, develop, and manufacture a full suite of solid state power amplifier modules that are part of our standard COTS building blocks. Our Flight Termination System High Power Amplifiers and Space Ground Link System amplifiers are designed using these power amplifier modules.

SPACE GROUND LINK SYSTEM (SGLS)

The SGLSs have their own integral power supplies and microprocessor controller that senses, monitors and controls the performance and all functions of the SGLS including but not limited to:

RF output power adjust
Temperature/Thermostat shutdown
Forward/Reflected RF power levels
Power amplifier module current
Overall SGLS voltage and current

All of these functions can be controlled either locally or remotely. Additionally, some models in our product line have built-in redundancy. This feature results in minimal RF power reduction in the event of a power amplifier module failure.

Our SGLSs are modular in design, allowing additional power amplifier modules to be added for higher power levels. We use high-power low insertion loss combining techniques. This technique requires fewer power modules while maintaining a robust and reliable system design. Our diversified and comprehensive product line includes systems operating in Class "A", "AB", and Pulse configurations with power levels from 1 watt to Multi-Kilowatts. The operating frequencies ranges from VHF to Ku-Band, and are designed for indoor or outdoor operation where rigorous environmental conditions persist.
