LNA 60dB D100
#23
Osmisljavanje rasporeda i odabir komponenti pa ako neko zna link ili komponentu gdje se lako nabave 68uF PET rastera 27.5mm i visine MAX od 33mm posto odabrano kuciste ima tu maximalnu visinu u koje stane taj DC Blocking kondenzator, pa sam nasao da B32524 ima u visini od 31,5mm ali ga nigdje nema na lageru, moze i WIMA...

Ovako je planirani raspored BNC konektori su na PCB-u zalemljeni INPUT, OUT-Hi-Pass, OUT-Low-Pass a dva velika plava elektrolita su tu DC blockeri, i plan je ispod tih elektrolita stavit na donjoj strani buffere za OUT konektore da cim budu blize bufferu, a desno od tih plavih kondenzatora sa gornje strane 2xLNA i sa iste te donje strane 2xLNA tako da ih imamo 4xLNA. Na desnoj strani PCB-a ce biti konektor za baterije i spajanje na tipkalo ON/OFF koje u sebi ima malu crvenu LED i tu cemo dodati jedan NE555 koji prati stanje baterije pa kad padne ispod 7,2V da LED-ica u tom ON/OFF konektoru blinka i dajuci do znanja korisniku da su dvije 9V baterije pri kraju svog zivotnog vijeka i da ih treba zamjeniti.

Sada je fokus na DC-Blockeru i trazim 68uF dva komada rastera 27,5mm i visine max 33mm...kuciste je odabrano OVO. Mislim da ce biti taman sirina od 70mm za PCB posto imamo veliko kuciste i punjo PNP i NPN bjt pa da se to sve stisne a sa tim kucistem imamo i izolaciju i izgledat ce profi i imaju kinezi customizaciju pa se lako stave natpisi i izbuse rupe prednje za BNC konektore i iza jedna rupa za push ON/OFF button a sve po povoljnoj cijeni. Crna mat boja kutije daje profesionalni izgled instrumenta. A za unutarnji shielding se stavi kuhinjska ALU folija i prekriju komponente i onda se stavi u tu kutiju.

Naziv projekta je OME φMAGOS LNA

Evo neko razmisljanje rasporeda:
