LNA 60dB D100
#71
Naravno, pogledaj crtu ispod P2 i iznad P1 tu je 2mm od ruba, i zato je tu da ne prilazim toj crti, a izlazni Buffer kad dodjem do routinga do njega morak okrenuti drugacije inace ce mi se TAB dodirivati sa unutarnjim dijelom lezista kutije.

Odlicno zapazanje, zato sam stavio crte 2mm od velicine PCB-a da se jos odmaknem od njih 0,508mm tako da nista se ne dodiruje.

Na kraju kad dodjem na LNA routing i komponente cu staviti 4 rupice da se stavi ALU pleh i zalemi za te rupe (mozda ima gotovo rjesenje recimo kocka povrsine xx2 pa da bude jos shielding), a unutar kutije sa sve strane se polijepi ona EMI traka pa netreba vise nikakvih kutija izvana, jer cemo imati trostruku zastiti EMI-ja, PCB GND shielding, ALU shielding, EMI traka unutar kucista poljepljena na unutarnju stranu kucista te samo kuciste Aluminijsko crno eloksirano debljine 2mm...dakle 4-struka zastita...ako ce to da probije EMI onda ja nisam pametan :-)

Na kraju jos moram i staviti unutra 2x9V baterije punjive i na izlaz dva USB-C konektora ali kupio sam nedavno punjive AA i AAA sa USB-C konektorom i unutra je switcher koji 3,7V smanjuje na 1,5V, posto switcher ima svoju frekvenciju radnu neznam koliko punjive baterije su pozeljne unutar kucista gdje je LNA pojacanje od 60dB.

Treba vidjeti koliko su duracell 9V mAh i koliko sklopovi trose, pa posto mjerenje ne radimo nekoliko sati nego nekoliko minuta da se te baterije stave i sa NE555 indikator prazne baterije, ali o tome cemo kad dodje vrijeme.
