The LNF-VTL_WR12B from Low Noise Factory is a Cryogenic Noise Source with a frequency range from 52 to 97 GHz. It is based on a variable temperature waveguide termination with a WR-12 port. This termination is made of a crystal quartz chip with a resistive film, a 50-ohm heater resistor, and a precision temperature sensor. It integrates the Lakeshore DT-670A1 Series temperature sensor which requires a suitable temperature monitor to supply a constant current of 10 μA, to measure the voltage and display the corresponding temperature. The noise source is available in a module that measures 33 x 28 x 18 mm with a WR-12 waveguide output interface (UG-387/U flange).
