  1. Divizoare de Putere Cuploare Directionale

  2. Proprietati de baza ale cuploarelor directionaleCircuite cu trei porti Reciproc > Adaptare simultana la toate portile Fara pierderi > Un circuit cu trei porti NU poate fi fara pierderi, reciproc si adaptat simultan la toate portile

  3. Circuitul fara pierderi si adaptat simultan la toate portile este nereciproc 1{ CIRCULATOR > 2{

  4. Circuitul fara pierderi si reciproc poate fi adaptat doar la doua porti > Linie fara pierderi adaptata + Poarta dezadaptata

  5. Circuit reciproc si adaptat la toate portile trebuie sa fie cu pierderi Divizorul de putere cu izolare intre portile de iesire

  6. Proprietati de baza ale cuploarelor directionaleCircuite cu patru porti > Reciproc Adaptare simultana la toate portile + (11) (13) Fara pierderi (14a) = < (14b) 10 ecuatii (14c) (14d) (15)

  7. Cazul 1 (11) si (13) > Cuplor directional (14a) si (14b) > Alegem: (14b) si (14d) > (15) > Cuplor antisimetric Cuplor simetric (14a) >

  8. Cazul 2 { (11) si (13) > Alegem: (14a) > Cuplor directional Caz banal

  9. CONCLUZIE Orice circuit cu patru porti, reciproc, fara pierderi si adaptat la toate portile este un cuplor directional

  10. Cuplor directional Cuplaj Directivitate Izolare

  11. Cuplor hibrid Cuplorul hibrid este cuplorul directional de 3 dB Cuplor hibrid in inel Cuplor hibrid in cuadratura
