Attached is a spreadsheet detailing the measurement of the ADL5565 NF, for 5V and 15.5 dB gain setting on an evaluation board. The result is plotted below.
The evaluation board was modified to remove the output attenuator and the input/output baluns were replaced with Minicircuits TCM1-43X+ to improve the frequency response. Balun loss was subtracted off from the measurements to obtain the NF of the DUT . The data points at 200 & 500 MHz deviates slightly from the datasheet, but the rest of the measurements shows how NF increases above 1 GHz.
