Hello,
in a very narrowband application working at RF 10 GHz, I would like to downconvert a signal having a relevant content at very low baseband frequencies (100 Hz to 500 kHz) . Unfortunately I was not able to find in the data sheet Noise figure measurements for baseband frequencies below 100 MHz. Would it be possible to have a deeper insight of this part performances for close to DC baseband frequencies? In case the part will be used at 10.4 GHz are there available graph or should I simply add a small degradation (1 dB?) degradation to your figures taken at 10 GHz?
Thanks.
Luca
