TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • 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.

  • 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.

  • VCO Measurements With FSPN Phase Noise Analyzer

    This application note provides a short technical introduction to voltage-controlled oscillators and explains the most common and the most important measurements made during the VCO characterization process.

  • 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.

  • 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.
