RF Noise Sources

RF noise sources are modules that are used to generate a fixed amount of noise required when trying to simulate real world conditions in the lab. A noise source basically produces random noise at required frequencies which is then mixed with the signal of the DuT (Device under Test).

Here is a list of some important parameters when looking for RF noise sources:

Excess Noise Ratio (ENR): For accurate calibration or measurement, it’s important to know that how much random noise is mixed with the original signal. It is also required to evaluate the effect of temperature changes and supply voltage variations on the random injected noise. That’s why the output ENR of the Noise source is required to be measured accurately.

Signal-to-noise Ratio (SNR): The SNR compares the desired signal power to the noise power and it’s always measured with respect to the frequency. Usually, ‘average’ SNR value is derived rather than ‘instantaneous’.

Noise Figure (NF): The noise figure tells how much the signal’s SNR degrades as it passes through that component or system. It is the ratio of input SNR to the output SNR.

Everything RF has listed precision calibrated waveguide noise sources, Millimeter-wave, and Broadband High ENR noise sources from the leading manufacturers. Use the search tool to find noise sources based on your required specification. Once you find a list of matching products, you can view detailed product information, download datasheet and request a quotation. Your requirement will be sent to the manufacturer of the product and their distributors in your region.
