Travelling wave tubes are vacuum devices with electron beams that couple to a microwave frequency electromagnetic signal propagating in the direction of the beam. Energy is transferred to the microwave signal, and the device generally behaves as an amplifier. A suite of software has been created, which allows very fast automated analysis of some types of travelling wave tube. This white paper delves into the design and use of this software to be used for determining the electrical characteristics of traveling wave tubes.
A radar transmitter is generally required to amplify a low noise coherent RF waveform. This waveform is generally provided by a radar RF exciter and can be fixed frequency, frequency chirped, or phase modulated during the radar transmitter pulse. It is important that the transmitter system amplifies this pulsed signal to a high power whilst maintaining its coherence and its fidelity. This paper covers an approach to the design of high voltage power supply units for operating traveling wave tube amplifiers in pulse doppler radar transmitter sub‐systems where ultra-low noise RF output is mandatory.
TMD has been involved for many years in all aspects of Electronic Warfare, Directed Energy Weapons (DEW) and associated systems, where the generation of RF power is required. They offer an array of broadband, narrow band, CW, and pulsed systems with operative power ranging from watts to megawatts.
This white paper explains how to compute cross-coupling effects between a cable bundle and 3G antenna mounted on a vehicle through the utilization of the cable modeling interface in FEKO. It also demonstrates the FEKO GUI elements that are useful for setting up an investigation into the cross-coupling between transmitters and cable bundles.

The SKY59269-702LF is a four-throw (SP4T) switch is designed for antenna tuning applications that require very low RON and COFF, and high VPK. The switch can be used for either series or shunt tuning applications. It is provided in a compact 12-pin, 1.6 x 1.6 x 0.45 mm (typical) QFN package that meets requirements for board-level assembly.
Skyworks offers the SKY59269-702LF four-throw (SP4T) switch is designed for antenna tuning applications that require very low RON and COFF, and high VPK. The switch can be used for either series or shunt tuning applications. Depending on the register setting, the antenna port can be connected to one of the four switched RF outputs or to multiple pre-defined outputs simultaneously, while the other RF ports are in isolation state to the antenna port.
The Orange Book of Knowledge (OBK) has grown into much more than we at AR could have ever imagined. For many engineers, this resource book has turned into the “go-to” source for everything and anything related to EMC.
The AR Catalog for RF and EMC testing features the new low cost Universal “U” series amplifiers with the widest bandwidth in the industry, covering the 10 kHz to 1000 MHz frequency range and up to 25 watts CW. Applications for these amplifiers are almost limitless but include lab use, R&D, EMC testing, antenna testing, and watt meter calibration. Additional catalog highlights include new RF solid state CW Amplifiers, pulsed amplifiers, TWTAs, details on HIRF systems components, and reference to a new product demo video on the 6-18 GHz amplifier series.
