lucicop Posted April 27, 2006 Share Posted April 27, 2006 Salut,Vreau sa fac un transmitator RF clasic, cu rezonator SAW si un tranzistor, pe frecventa de 433.92 MHz. Problema e ca in schema de referinta e trecut un tranzistor NE94433 si nu prea se gaseste pe la noi, si am inteles ca nu prea se mai fabrica. Stiti cumva un echivalent la fel de bun ?Lucian Link to comment
Ovidanie Posted April 27, 2006 Share Posted April 27, 2006 BFR 93.Asta am folosit pentru emitator cu rezonator SAW si un tranzistor.Pun foto cind gasesc un aparat care stie macro ca mi-au iesit niste cablaje mici-mititele... Link to comment
lucicop Posted April 28, 2006 Author Share Posted April 28, 2006 Din cate vad in datasheetul lui are hFE cam mic. Nu e important la astea sa aiba hFE cat mai mare ? Eu m-am gandit sa folosesc un MMBTH10 sau BFS17A. Link to comment
