Focus Microwaves - Noise Modules
of the cold-source noise figure measurement technique. This specific technique requires a noise source to determine the kBG (gain-bandwidth constant) of the system and a passive mechanical tuner is used to characterize the noise receiver across both the impedance and frequency space. This step is imperative to obtain fully vector-source-corrected measurements.
A RF down conversion stage might be required if the frequency of noise measured exceeds the receiver’s bandwidth. Focus offers noise modules which support down conversion for optimal speed and performance.
