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.

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.

An Introduction To Direction Finding Methodologies
All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity. Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

Making Higher Accuracy Oscilloscope Measurements
One of the most important functional blocks in a digital oscilloscope is the analog-to-digital converter or ADC. This white paper explains why ADC resolution has become a more important consideration in oscilloscopes, especially for measuring small signal details.
