TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• 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.

• Harmonic Measurement For IEC 61000-4-3 And Other Radiated Immunity Standards

  Amplifiers exhibiting significant harmonic distortion in immunity test systems can exhibit broadband characteristics that result in measurement uncertainty and unacceptable errors. This app note addresses acceptable harmonic measurement standards and other radiated immunity standards.

• Top 5 Strategies For 5G Component Characterization And Test

  Component manufacturers need to deploy effective strategies for characterization and test regardless of the component types. This white paper presents five strategies for 5G component characterization and testing.

• VCO Measurements With FSPN Phase Noise Analyzer

  This application note provides a short technical introduction to voltage-controlled oscillators and explains the most common and the most important measurements made during the VCO characterization process.
