Currently we are trying the reception in 2.45 GHz. We have one RF switch IC and an external LNA (ADL5523) on the path. DC blocking capacitors are added as per recommendations. Also board uses external...
View ArticleRe: ADuCM360, how should I connect to a PT1000?
We suggest using the PGA with a gain of 2.We base our idea on the following:PT1000 resistance range is ~670 ohms to 2840 ohms.We suggest 6800ohms for the Reference resistor - usually connected in...
