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.

Low VSWR and high GAIN enable efficient electromagnetic wave radiation.
-
Wide field uniformity reduces the number of times of movement of the antenna when radiating the EUT.
-
Since the maximum point of the near electric field distribution for each frequency is at the center, enables radiation on the EUT based on the axis of the antenna. Hence, significantly simplifies test point alignment.
