Abstract
A method to determine noise parameters of a scalable device, is presented in which the determination of the noise parameters of the scalable device is independent of the model adopted for the device. The scalable device is connected as part of a test circuit including a noise source, a recirculator, a first power detector and a second power detector. The first power detector is connected to the recirculator and between the noise source and the scalable device and the second detector is connected to the device under test.

A method for determining noise parameters of a scalable device, wherein the determination of the noise parameters of the scalable device is independent of model adopted for the device, the method comprising:
- taking a measurement, wherein taking the measurement comprises:
- detecting, using a first power detector, a first noise power, wherein the first noise power is generated by a device under test (DUT) and is directed, by a recirculator, to the first power detector, and
- detecting, using a second power detector, a second noise power, wherein the second noise power is generated by the DUT and is directed, by the DUT, to the second power detector;
- changing a size of the DUT and repeating the measurement;
- and
- determining the noise parameters based on the first noise power, the second noise power, wherein the noise parameters include a noise figure from the noise source to the first power detector, and wherein determining the noise parameters comprises determining the noise figure based on a correlation matrix of noise parameters for the DUT.
A device for detecting noise parameters, the device comprising:
- a noise source;
- a recirculator coupled to the noise source;
- a device under test (DUT) coupled to the recirculator, wherein the DUT is configured to generate a first noise power and a second noise power, wherein the DUT is configured to be replaceable;
- a first power detector coupled to the recirculator and further coupled between the noise source and the DUT, wherein the recirculator is configured to direct the first noise power to the first power detector;
- and
- a second power detector coupled to the DUT, wherein the DUT is configured to direct the second noise power to the second power detector, wherein the device is configured to determine a noise figure from the noise source to the first power detector based on a correlation matrix of noise parameters for the DUT.
