33 GHz – 50 GHz Broadband Calibrated Noise Source

870B/383, Q-band, ENR 15.5 dB, VSWR 1.3:1


These RF noise source components generate noise output ENR levels ranging from 12 to 30 dB with stability over temperature.

The noise source can be integrated with Mi-wave’s 115 series high-quality Faraday isolator to improve the port return loss and load pull for more reliable and accurate noise figure measurements. The isolator provides almost constant output impedance as the noise source bias is switched on and off. The isolator also protects the noise diode from incident RF power. Note: The customer can choose to include Isolator with the noise source.

Noise Sources 870

A noise source basically produces random noise at required frequencies which is then mixed with the signal of the DuT (Device under Test). Applications of noise sources include noise figure measurement, millimeter-wave radiometers, automotive radar as well as research and development in modern high-frequency broadband wireless communication systems. A Waveguide port is standard for the RF output and a BNC female connector is standard for the bias input.
