Njikọ ntụzịaka VHF sitere na 130-180MHz JX-DC-130M180M-Nx
VHF band directional coupler sitere na 130-180MHz JX-DC-130M180M-Nx bụ otu ụdị RF pasive components emebere & mepụtara maka ọrịre site na Jingxin, nke nwere njirimara pụrụ iche na ntinye ntinye dị ala, obere olu, tụrụ LxWxH: 143mm x 37mm x 19mm.
The ugboro nke a coupler ekpuchi si 300-500MHz na Njikọta 6dB,10dB,15dB,20dB,30dB , nke na-arụ ọrụ n'okpuru ike nke 200W. Ejiri njikọ N-Female mepụta njikọ a, mana enwere ike ịgbanwere ya na ndị ọzọ dịka achọrọ. Na eserese na agba ojii, di na nwunye dị otú ahụ nwere ike iburu n'ọhịa ruo ogologo oge.
Dị ka e kwere ná nkwa, ihe niile RF pasive components sitere na Jingxin nwere akwụkwọ ikike afọ 3.
