Effortless Testing Of Direction Finding Devices – Amplitude Based
Together with multiple coupled R&S SMW200A vector signal generators, the R&S Pulse Sequencer allows performance characterization of all types of direction finding equipment such as devices that use amplitude comparison, interferometric or time difference of arrival (TDOA) techniques.

Linearity Of The JFET And MOSFET When In Saturation Over The Entire Cycle
Performing RF amplification in a way that is simultaneously linear and efficient has been a challenge in power amplifier (PA) design. Single transistor PAs can either be operated in a linear, but inefficient, current source mode of operation or as efficient, but nonlinear, switches. These techniques use two FETs, but this paper demonstrates that linear amplification can be achieved at high power with an efficiency greater than 60%, using a single FET.

Directivity And VSWR Measurements: Understanding Return Loss Measurements
The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.
