TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • 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.

  • 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.

  • VSWR Conversion To Reflected Power

    VSWR measures how efficiently RF power is transmitted through a load, with high VSWR indicating poor efficiency. Explore VSWR's relation to return loss, reflection coefficient, and mismatch loss.

  • De-Embedding Test Fixtures For High-Speed Digital Applications

    Test fixtures are commonly used in high-speed digital measurement to connect devices to measurement equipment. Characterization and analysis in time and frequency domains help remove the influence of these fixtures.

  • 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.
