LNA 60dB D100
#11
Naravno, cilj je iskoristiti remote sense da napon bude fixni, a i GND vodovi da budu u jednoj tocki a to je na ulaznim klemama preampa iz koje se svaki vod vodi do svog potrosaca da imamo ciste vodove i neunasamo smetnje jer je ovaj preamp jakoo brzi i treba misliti na svaku sitnicu kod designa PCB-a, vrlo zahtjevan projekt za routing.

Molio bih Dragan100 kad bude imao vremena dali moze revidirati shemu da radi na +/-15VDC posto THS4631 mu je to max dozvoljeni napon da radi, pa ce trebati preraditi i radne tocke sa 18V na 15V, dodati za izlazni kompozit trimpot, te naci SMD zamjene za TTA004 i TTC004B da budu u kucistu  SOT-223-4 ili slicnom da moze da se hladi preko PCB bakrene fleke.

Evo dokle sam stigao sa precrtavanjem sheme, ostaje jos precrtati izlazni Diamond Buffer i dodat jumpere na shematic te po revidiranoj shemi ispraviti vrijednost otpornika. Velicinu svih R i C sam stavio 1206 radi lakseg lemljenja :-)
