TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Testing A 24-28GHz Power Amplifier Using The 5G New Radio Test Standard

  In this white paper, we will introduce some of the main challenges in test and measurement of a device at mmWave frequencies, with a 26 GHz pioneer band defined for the UK between 24.25 - 27.5 GHz.

• 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.

• Solving Tomorrow's Obsolescence Challenges Today

  This white paper discusses best practices in operations implementation, hardware acquisition, and software design to reduce the sustainment burden of handling obsolescence in test systems long before the equipment goes end of life.

• Directivity And VSWR Measurements: Understanding Return Loss Measurements

  The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

• Wi-Fi Performance In A House With Two Routers

  Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. This example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth.
