Yokhala ndi amplifier yanzeru yosinthira mphamvu komanso chokulitsa mphamvu kuchokera kunja, ili ndi phindu lalikulu komanso mzere wapamwamba wa LDMOS transistor. · Kugwiritsa ntchito mphamvu pang'ono, kapangidwe kapamwamba kwambiri, kumathandizira kwambiri mphamvu yotumizira, kuchepetsa zinthu zosokoneza zosagwirizana. Ili ndi ntchito ya AGC kuti iwonetsetse kukhazikika komanso kudalirika kwazinthu. Ntchito zowunikira ma alarm ndi ma sign zimawonetsedwa ndi LED. The switching regulator, osiyanasiyana bata, mkulu dzuwa.
