I measured the Noise Figure (NF) and the Gain (G) of the HMC996LP4E on the EvalBoard using a noise-gain analyser. The HMC996 was biased at Vg1,2 = -0.75V, Idd = 120mA, Vctrl = -4.5V, Vdd1,2 = 5V, operating bandwidth 9.2 - 9.5 GHz.
The measured results are reported in the picture below, as you can see the Gain is the typical, but the NF is more than 1.5dB higher than the specification in the band 9.2GHz to 9.5GHz.
Could you please comment on that? In particular, are the specification for the EvalBoard that different in terms of NF respect to the component specification (NF=2dB typ.)?Why this discrepancy?
Do you think the measurement setup is not correct?
Could the component not working properly?
