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.

• Ray-Optical Modeling Of Wireless Coverage Enhancement Using Engineered Electromagnetic Surfaces

  In this paper, results are presented of propagation experiments conducted to verify the accuracy of a novel ray-optical scattering model for EES.

• Measurement Setup For Phase Noise Test At Frequencies Above 50 GHz

  Recent semiconductor technologies require more of the frequency range beyond 50 GHz, especially in wideband applications, such as 802.11ad, microwave links, or automotive RADAR. Low phase noise is essential for these applications to work properly, and accurate measurement of phase noise is needed to improve the performance. However, test setups at these frequencies become difficult, especially when cross correlation of two receive paths is needed to suppress additional phase noise.
