Cum functioneaza mixerul de antena dx 27

Recommended Posts

Salut.V-as fi recunoscator daca mi-ati explica cum functioneaza mixerul de antena din poza.E vorba de un mixer care face sa functioneze o statie radio citizen band si un aparat de radio cu aceeasi antena.Cum de la emisia statiei , nu se arde intrarea RF. a radioului.Releu de comutare nu are caci nu are alimentare. :nas: :cry: Il gasiti aici:http://www.lccom.ro/product_info.php?cPath=23_37&products_id=101

contine niste filtre pasive LC (trece sus) pe calea radioreceptorului, care permit trecerea semnalelor numai peste o anumita frecventa, numita frecventa de taiere. astfel frecventa de 27 mhz care este sub frecventa de taiere, este puternic atenuata. sau poate contine un filtru trece banda calculat pt gama 88-108 mhz.

Bun. Dar in momentul in care statia CB emite , cei 4 w,vor fi atenuati sa nu intre spre radio, dar vor fi atenuati definitiv deci nu vor mai fi nici in antena.

banuiesc ca filtrul este pe calea radioreceptorului, nu pe calea comuna care duce la antena.
