TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Compact Solution For Network Analysis In The mmWave Range

  The R&S^® ZNA vector network analyzer with integrated LO output and direct IF input options is a simple, cost-effective solution for 2-port and 4-port measurements using Rohde & Schwarz mmWave converters.

• Accurately Measure Your UWB Device's Time Of Flight

  The R&S®CMP200 radio communication tester together with the R&S®CM-Z300A time of flight kit provides an accurate setup for time of flight measurements – in validation, calibration and certification.

• Design And Implementation Of A Miniature X-Band Edge-Coupled Microstrip Bandpass Filter

  Microwave bandpass filters are the fundamental component used in many RF/microwave applications to eliminate interference from signals operating at nearby frequencies. This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator within Cadence AWR Design Environment software.

• Crowdsourcing Versus Mobile Network Testing

  The need for an objective evaluation of mobile network quality and performance drives two fundamentally different approaches, crowdsourcing, and mobile network testing.

• 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.
