SCALABLE SOLID STATE POWER AMPLIFIERS [ Liquid Cooled, CW & Pulse, HF to X-Band ]
Liquid Cooled RF Amplifier Systems

Unlimited power combining with hot swapping provides an affordable upgrade path for mission critical applications

A unique design architecture from Empower RF Systems is yielding unprecedented performance and scalability for liquid cooled SSPA’s delivering hundreds of kilowatts of pulse and CW power. This breakthrough design is being fielded using both LDMOS and GaN on SiC devices for user applications that include EW, Radar, Directed Energy, Satcom, EMC and RF Product Testing.

THE MOST FLEXIBLE AMPLIFIER SYSTEM AVAILABLE

Each amplifier “building block” includes an integrated power supply in its 2U chassis. This arrangement improves pulse droop performance while eliminating the risk of a single power supply failure taking the entire amplifier offline.

Narrow and broadband configurations are available from UHF to X Band CW or Pulsed. The architecture is the same regardless of frequency – RF configurations driven by output power requirements. Each amplifier drawer is fully “hot swappable” with proven dripless technology.

You can increase output power to an existing amplifier by adding 2U amplifier building blocks (in even numbers) or adding additional complete racks.

System Rack

Empower’s Next Generation liquid cooled amplifier is designed to stay ahead of the increasing complexities of the signal environment. The combination of embedded firmware, software, and real time processing/control allows for maximum flexibility and operation in any application. This single architecture is capable of user selectable multimode operation and can by dynamically configured. CW Amplifiers offer the same pulse performance as our pulsed amplifiers with no limit on duty cycle and the Pulsed amplifiers allow CW operation 7dB below rated peak power.

  • Performance Monitoring and Systems Reporting – Current, Voltage, Temperature down to the Pallet and Device Level
  • Continuous BIT, Down to the Device Level
  • Each 2U Amplifier “Building Block” is Digitally Set for Phase and Gain

SCALABLE UPGRADE PATHS
PLANNING FOR AN UNCERTAIN FUTUREE

Empower’s scalable solutions offer an affordable upgrade path for future power needs by adding hardware to an existing system.

Our solutions provides three levels of scalability which can be exercised independently or in any combination:

  • Increased number of 2U amplifier drawers per rack
  • For racks not fully populated, 2U amplifier drawers can be added in pairs

    A partial system contains an even number of 2U amplifier drawers (A full rack contains 16)

  • Increase number of racks
  • Full racks can be combined with additional 1, 2,3, or 5 racks

    For racks not fully populated, “like populated” racks can be combined

  • Increase the amplifier’s duty cycle for pulsed systems - consult factory
