  • A Practical Guide to Microwave Switch Selection for ATE Systems

    Several factors should be considered when selecting a microwave switch for ATE systems. These include frequency range, power level, reliability, low PIM, connector style, VSWR, isolation, insertion loss, repeatability, termination, phase or path length matching, and more. Details on these factors and others are explored in this application note.

  • Power Handling Considerations for SMD Terminations, Attenuators, and Resistors

    Power ratings for Anaren’s SMD Terminations, Attenuators, and Resistors are based off of the temperature at the solder interface where the solder is in contact with the SMD components. This application note describes the power rating of high power surface mount resistive products, as well as techniques for maximizing power handling performance of these products.

  • Selecting Oscillator Technology

    Selection of appropriate oscillator technology for an application can be critical to success or failure of a project. This paper discusses the three most common oscillator technologies in use today in time and frequency applications, namely Temperature Compensated Crystal Oscillators (TCXO), Oven Controlled Crystal Oscillators (OCXO), and Rubidium atomic oscillators (Rb oscillator).

  • High Temperature, High Power RF Life Testing Of GaN On SiC RF Power Transistors

    As GaN power device technology matures and gains acceptance in the market place, suppliers who provide products using this promising technology must prove its reliability. This article provides an overview of the testing approaches used to establish failure rates and will provide a comparison of DC and RF based HTOL methods.

  • Impact of Switching on ATE Measurements

    This application discusses the factors that should be considered when designing or implementing an ATE switching system. Some of the factors discussed in detail include noise, bandwidth limitations, measurement uncertainty, grounding, and accuracy.
