What Is Pulse Shaping?
The electromagnetic environment is changing at an increasing
pace, and thus the importance of electronic warfare (EW) system adaptability, flexibility,
and innovation has also increased. However the RF high power system amplifier has not evolved
in any significant way since the inclusion of the microcontroller twenty years ago. That's
a remarkable statement given the advancements seen in virtually every other application of
electronic products and systems. Not only are innovative technologies needed, the EW systems
engineer will benefit greatly from the new capabilities that a software defined, re-configurable,
smart high power amplifier can provide.
One such capability is the breakthrough for
pulse shaping where the HPA reproduces the pulse with extreme high fidelity
and by doing so removes that task from the system integrator. Additional benefits include
simplifying external hardware, lowering overall cost and improving SWaP.
Pulse Shaping in High Power Solid State Jamming Amplifiers
When: Thursday, November 30, 12 pm to 1:30 pm
Location: Marriott Marquis Hotel Marquis Ballroom, Meeting Level
Presenter: Paulo Correa
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. In this technical session, Paulo Correa will describe a new high power amplifier
architecture with built in real time feedback that is capable of matching the input signal
shape, minimizing droop, overshoot, ringing, rise and fall times.
Real world examples and data will be shown from an amplifier simulating pulsed jamming
scenarios to illustrate the performance problems and their sources within the HPA and why
future amplifier performance issues will be resolved within the amplifier using real time
digital correction. Finally, the workshop will illustrate the benefits of the proposed amplifier
- Real time optimization of the PA pulse characteristics
- Reduce system engineering design time
- Reduce overall size and weight of the jamming system
- Reduced hardware to correct droop
- Adaptive digital correction of the pulse in the event of variable VSWR
Paulo Correa is Empower RF's CTO with 41 years of experience in RF and microwave with past
roles including Director of Advanced Studies at Thales and CTO at Thomson Broadcast and Multimedia.
With 13 patents to his name, Mr. Correa is also the architect of Empower's intelligent and
flexible Next Generation series of amplifiers.
RF Systems' Booth at AOC Convention
Empower RF Systems will be exhibiting at this year's AOC convention at Booth 314. Empower
RF Systems is conducting remote live demonstrations of our broadband, high power 1KW, 1 to
3 GHz amplifier. The amplifier will be housed at our headquarters in Los Angeles and viewed
in the AOC exhibit venue with live streaming video while remotely controlling the amplifier
from the exhibit floor through a standard web browser.
