Application Notes & Tech Notes

  1. A Practical Guide To Noise In Frequency Conversions 2/17/2023

    When RF engineers encounter noise figure problems with the receiver, they can mistakenly conclude that the mixer is not performing properly. In this article, we will illuminate potentially overlooked noise sources in a typical converter.

  2. How Do Amplifiers Affect Signal Phase Noise? 2/17/2023

    Phase noise is critical to systems requiring precise frequency stability. In extremely low phase noise systems, the amplifier phase noise contribution is considered in the signal chain’s phase noise performance

  3. Debugging Surface Mount Footprints With Time-Domain Reflectometry 2/17/2023

    Without a means to determine fault locations with the naked eye, Time-domain reflectometry (TDR) proves a powerful tool in visualizing impedance types and variations on a microstrip.

  4. Marki's MMIC Filters are Hot, Hot, Hot! 2/16/2023

    GaAs MMIC filters offer the best combination of performance, cost, and consistency – recent testing further indicates that these filters maintain consistency with low variability over temperature and high power handling capabilities.
