Passive-intermodulation (PIM) performance is essential to the successful operation of many wireless communications systems, although it typically must be tested with a number of fairly high-level test tones.
This white paper covers the basics of non-signaling test from 10 MHz to 6 GHz, the technology models of implementing a non-signaling test setup, approaches to lowering the overall test cost, as well as turnkey chipset-specific calibration and verification solution....More
With more and more radio technologies introduced, as well as the concept of HetNet, the testing for mobile devices becomes ever increasingly complex. A cellular phone’s neighbor cell detection capability is important to its overall performance, not only for mobility behavior such as re-selection and handover but also for cellular-assisted location estimation....More
Cosite challenges are increasing exponentially alongside the growth of radio systems used in most applications. Simulation software that predicts cosite issues and optimizes antenna placement has recently been enhanced with libraries of common radio systems....More
