TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Combining On-Wafer VNA And Spectrum Analyzer Measurements

  This app note describes how S-parameters and spectrum analysis can be monitored simultaneously from 70 kHz to 110 GHz using the VectorStar ME7838A, the Spectrum Master MS2760A, and the Anritsu MN25110A W1 coaxial precision directional coupler.

• 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.

• 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.
