Bravo Dragane!

S ulaznim šumom se može ići na 0,25nv/rtHz (4xJFE2140), ali moje iskustvo je da nema velike potrebe za tako niskim šumom.
Za mene će tu biti dovoljno 0,5nV/rtHz, tj. 2xJFE2140.
Već dugo koristim dva LNA (Groner: 0,4nV/rtHz, Wurcer: 0,7nV/rtHz) i oba mi daju praktično iste rezultate kod merenja šuma regulatora, čak i kod onih sa šumom od 2nV/rtHz.

Meni će biti potrebna dva "nova" LNA jer sa postojećom opremom ne mogu da merim THD uređaja sa balansnim izlazom.
Jedan LNA ću svakako napraviti kao prototip, a drugi će ga slediti.
