Hot Swappable Liquid-Cooled Solid-State Power Amplifier Platform for Mission Critical Applications

Hot Swappable Liquid-Cooled Solid-State Power Amplifier Platform for Mission Critical Applications

Empower RF has developed a unique scalable, liquid-cooled solid-state power amplifier (SSPA) platform for mission critical applications. It is based on a unique design architecture that yields unprecedented performance and scalability for liquid-cooled SSPA’s delivering hundreds of kilowatts of pulse and CW power. Based on the power level required, amplifier building blocks can be added or removed (hot swappable) to the system. This breakthrough design has been developed using both LDMOS and GaN on SiC devices for user applications that include EW, Radar, Directed Energy, SATCOM, EMC and RF Product Testing.

Each amplifier “building block” is fully “hot swappable”  and 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 for CW or Pulsed requirements. The architecture is the same regardless of frequency – RF configurations driven by output power requirements. You can increase output power to an existing amplifier by adding 2U amplifier building blocks (in even numbers) or adding additional complete racks.

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.

The SSPA allows the user to also select the required output power control parameters (automatic gain control (AGC), automatic level control (ALC)), signal modulation schemes (CDMA, FSK, QPSK, OFDM), and input/output power type (CW, RMS, peak) to cater to their needs.

Scalable Upgrade Paths Planning for an Uncertain Future

This scalable RF Power Amplification solution offer an affordable upgrade path for future power needs by adding hardware to an existing system. This platform provides three levels of scalability which can be exercised independently or in any combination:

  • Increased number of 2U amplifier drawers per rack
  • Increase number of racks
  • Increase the amplifier’s duty cycle for pulsed systems - consult factory
