Noise Receiver Modules and Noise Switching Modules

Noise Parameters are the non-50Ω extensions of Noise Figure, and are an important modeling and model validation tool to understand how a device-undertest’s performance changes as a function of source impedance. Noise Parameter measurements are typically performed using a Vector Network Analyzer (VNA) to measure the S-Parameters of the DUT, and a Noise Analyzer (either Noise Figure Analyzer NFA or Spectrum Analyzer SA) to measure the noise power of the DUT. Noise parameters are calculated from a combination of known source impedances, S-parameters and noise powers.

Noise Receivers and Noise Receiver Calibration

The Noise Receiver consists of the component chain from the DUT output to, and including, the Noise Analyzer. The minimum Noise Figure (Fmin) of the Noise Receiver will affect the minimum accurately measurable Noise Figure of the DUT by increasing the sensitivity of the receiver. Therefore it is critical to provide a Noise Receiver with the lowest Fmin possible. In addition, Noise Analyzers may not be available at the frequencies of interest and in these cases it is common to use a downconverter chain to lower the frequency of the signal to one that can be measured by the Noise Analyzer. Maury’s family of MT7553-series Noise Receiver Modules assist in doing exactly these things.
