Igice cy'inyuma
A. Aho gupimira umusaruro
Umuyoboro w'igerageza ry'amashusho, -20dB;
B. Umusaruro wa RF
Moduli ya Multiplexer yahinduwe, nyuma yo kuvanga umusaruro wa RF;
C. Igenzura ry'umusaruro wa RF
Agapfundo, urwego rw'umusaruro wa RF rushobora guhindurwa;
D. Ingufu zisohoka mu buryo bwa "power cascade"
Gushyira modulators nyinshi mu mwanya wazo, ushobora gukwirakwiza umusaruro wazo mu zindi modulators z'amashanyarazi kugira ngo ugabanye ikoreshwa ry'amashanyarazi; witondere kudasukiranya inshuro zirenze 5 kugira ngo wirinde umuriro mwinshi.
