Empower RF Systems has introduced Next generation scalable solid-state power amplifiers based on an architecture that can yield unprecedented performance and scalability for liquid cooled SSPA’s delivering hundreds of kilowatts of pulse and CW power. The system can be scaled up in power by using (stacking) multiple building blocks (amplifiers). Each amplifier “building block” includes an integrated power supply in its 2U chassis. The power combining feature with hot-swapping provides an affordable upgrade path for mission-critical applications. This breakthrough design is fielded using both LDMOS and GaN on SiC devices for user applications that include EW, Radar, Directed Energy, Satcom, EMC, and RF Product Testing.
This scalable 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 configurations driven by output power requirements. Each amplifier drawer is fully hot-swappable with proven dripless technology.
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 be dynamically configured. CW Amplifiers offer the same pulse performance as our pulsed amplifiers with no limit on the duty cycle and the pulsed amplifiers allow CW operation 7 dB below rated peak power.
Key Features of Liquid-cooled Systems:
- Liquid Cooled Scalable Power Architecture in CW or Pulse Configurations.
- No single point of RF active device failure.
- Distributed power supplies.
- Full frontal “on air” hot-swapping.
- The system will remain operational and “On the Air” with graceful power degradation.
- Asymmetrical and random pulse width and duty cycle operation.
- Short and long pulse capabilities - from 100 ns to 500 usec.
- Full digital peak and RMS detection for accurate metering.
- No external cabling, and full backplane implementation.
- Ethernet rapid spanning-tree architecture for network redundancy.
- Performance monitoring and systems reporting – current, voltage, temperature down to the pallet and device level.
- Continuous BIT, and down to the device level.
