Empower RF Gen3 Amplifier System - Demonstration of PA Field Replaceable Feature
Fast Field Replacement (FFR) of an amplifier booster module in Empower’s liquid cooled scalable architecture is a significant capability for mission critical applications with the added benefit of lowering service and spares cost. The video you are watching demonstrates the ease and speed of replacing a faulty booster while the amplifier is transmitting. The amplifier booster modules are removed from the front, no access to the rear is required. Blind mate electrical connections and dripless cooling manifold connections on the rack backplane make this possible. Shown is the model 2244 – Pulsed 8KW L band, 1 to 1.4GHz with up to 500 usec pulse widths and 20% duty cycles.
Pulse Droop Correction Demonstration
This video describes and demonstrates Pulse Droop correction on a C band long duty cycle SSPA. This is a technology developed at Empower RF Systems and enabled by the computational power and very high speed data rates we build into our newest generation of amplifiers.

Smart RF Amplifier can simplify your system hardware and software development
Jon Jacocks, Empower RF CEO, discusses the topic of simplifying your test setup with a smart amplifier. It’s common for integrators to build their own feedback control system around the standard RF amplifier. The typical setup includes external dual directional coupler, power sensors, power meter, signal generator, and PC running either your own custom code or heavily customized Matlab or Labview coding. Besides this approach being a very slow feedback control loop, the cost of system engineering and coding is high and the development time lengthens project schedules. Jon presents this topic and how a Smart amplifier can simplify your system hardware and software development.
A Modern Solid State Architecture for Very High Power Applications
Watch this in depth 30 minute video presentation describing a modern architecture and its benefits for implementing RF & microwave SSPAs in the tens and hundreds of kilowatts. Scalability of a modular design that is repeatable and deterministic is covered. MTBF's and reliability vs. traditional SSPA and tube technologies is discussed. The “Always on air” concept with hot swapping is discussed as are the Implications to total mission cost and effectiveness for critical high power applications. Empower’s CTO, Paulo Correa, discusses some of the more technical subject matter in the topics below:
Pulse Shape Duplication for High Power SSPA's
High power amplifiers do a poor job duplicating the input signal without distortions. Due to the transient response of the amplifier the output will over shoot, ring and droop, introducing undesired low and high frequency components into other parts of the spectrum. Pulse shaping, as it is done today, is an effort to fix fidelity issues caused by the transmitting amplifier and is accomplished by a combination of imperfect methods, most external to the amplifier. Presented at IMS 2021, George Bollendorf explains a new approach that matches input pulse signal shape, minimizes droop, overshoot, ringing, rise and fall times.
MilSpec Amplifier Shake Test at Full Power
Watch Empower RF Systems’ COTS 5U architecture deliver a full Kilowatt while shaken at 40G at a certified MilSpec test lab. Empower has developed a virtual “connector-less” internal architecture in our Next Generation family of RF and microwave amplifiers. Because of this electro-mechanical design these COTS amplifiers find themselves fielded in some airborne platforms and many land and naval applications. If your use case isn’t as demanding you still benefit from the inherently rugged design when moving around the lab, campus, or shipping between facilities.
