  3. All About RF Power Splitters 5/17/2024

    Dive into the world of RF power splitters, from Wilkinson to directional couplers, and discover their types, classes, and key performance metrics essential for efficient signal distribution in RF systems.

  4. Advanced Calibration Techniques For IQ Mixers 5/17/2024

    Discover how advanced calibration methods tackle challenges in IQ mixers, ensuring superior performance crucial for vector signal analyzers and communication architectures.

  5. Disconnecting The Dots: Stellar Constellations With Stellar Connectorized Parts 8/2/2023

    Marki showcased a mmWave up- and down-conversion chain using a fully coaxial connectorized lineup operating at 81GHz, demonstrating the power and flexibility of their 1.0mm connectorized product family at IMS 2023.

  6. Using The MMIQ-0218 As A Vector Modulator 3/13/2023

    The proper way to apply a DC current to the mixer is through a bias tee, allowing the high-frequency output from the mixer to absorb rather than reflect back into the mixer, potentially causing ripple or other degradation to the performance of the IQ mixer as a vector modulator.

  7. LO To RF Isolations: Why A 10dB Buffer Is Best 3/13/2023

    The LO to RF isolation of a mixer is a critical performance specification in most broadband applications. LO feedthrough can not only contaminate a system, but the noise fed from the LO path can degrade a system’s noise figure.
