Until recently, Traveling Wave Tube Amplifier (TWTA) technology has been the only available option for pulsed field generation. AR now offers high-power solid state pulsed amplifiers at various frequency ranges and output power levels to meet several standards. This white paper presents some of the key features and benefits of AR’s new line of amplifiers, and how to generate high speed and accurate peak RF power measurement capabilities that are ideal for EMC testing, manufacturing testing/troubleshooting, amplifier design/development, and research.
This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.
Time Difference Of Arrival (TDOA), also called multilateration, is a technique for RF emitter geolocation using three or more receivers with algorithms to locate a signal source from the different arrival times at the receivers. This article explains factors that can have an impact on overall TDOA accuracy.
To classify a signal in RF spectrum intelligence gathering, the user must recognize a specific pattern associated with the modulation. Additionally, to recognize a remarkable signal present in received data, the pattern must be distinguished from the noise. Pattern recognition is something that the human brain is good at, but it is more desirable to automate these applications for efficiency and to avoid errors cause by human fatigue.
The Fischer Plastic Series is a family of high performance, fully insulated plastic connector bodies that are all compatible with Fischer’s metallic connectors.
