LNA 60dB D100
#77
(03-11-2024, 01:26 PM)savan Wrote: Ok, prepravicu i sacekacu da zavrsis sa simulacijom da ne rutiram bezveze pa posle da prepravljam, nije bas jednostavan sklop! Dragane gde je zvezdiste za gnd, na kojoj tacki? Treba li bom da okacim da pogledas dali je to to?

GND_referenca mora biti GND_IN, tu se svode merenja sa ovim LNA (IN-GND_IN). Tačka GND ulaznog BNCja
na tu GND tačku/zvezdište idu onda posebno:

-GND ulaznih otpornika RNP1,2,3 (najverovatnije jih nečemo  stavljati, ali neka jim je platz tu)
-GND ulazne karike DCservoa, taj otpor.dijeltelj odmah nakon Cin (R35, R36, R37)
-GND SUM opampa U7 pin +IN i GND njegovog izlaznog opterečenja R40
-GND DCservoa U7 R38 i C32
-moduli LNA 60dB GND od NFB_bottom R8 (svi R8, od svakog modula posebno vod)
-GND MFBfiltracije HPF U1 R13, R19, R31
-onda Butterworth filtracija LPF U3 C12, C13
-kod izlaznih Buffera U4 i U5 imamo C5 i C6 na GND
-ostaju izlazni konektori BNC 100K i WideBand
-napajanje +/-9V takodjer ima svoj GND u zvezdištu

-tu idu i svi GND Shilding-i koje stavlljamo po PCBju, oklopi GND, GND_kutijica... 
!!!svaka fleka Shildinga SAMO U JEDNOJ TAČKI spaja se na/prema tom GND zvezdištu!!!


Okači ili pošalji mi EasyEda file sheme, pa ču tamo lakše/brže da vidim šta si odabrao,
pa ako zatreba popravka odabira elementa odradim "na licu mesta", 
pa kasnije vračam popravljen file.
A može da ucrtam/obrišem još po koji element!?... znaj ga sad! :-)
