TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• Small Cell Testing In FR2

  In the era of 5G, small cells have become pivotal in network densification. Explore the essential testing aspects of small cell devices throughout their product life cycle.

• Field Probe Correction Factors

  To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.

• RF Test Setup For Measuring Power & Harmonics

  Power measurement is accomplished by using a high-power calibrated coupler or attenuator, which gets attached to the Amplifier RF output connector. Harmonics are recorded similarly by increasing the input drive from the signal source. 

• On-Wafer Characterization At sub-THz Frequencies

  New technologies and applications extend into sub-THz frequencies in the D band and beyond. New semiconductor technologies and processes need to be commercialized to support these efforts.
