Chiyambi cha RF Cable

Chiyambi cha RF Cable

Kuphatikiza pa kuchuluka kwa ma frequency, ma wave wave ratio, kutayika koyika ndi zinthu zina, kusankha kolondola kwa zida za RF kuyeneranso kuganizira mawonekedwe amakina a chingwe, malo ogwirira ntchito ndi zofunikira zogwiritsira ntchito, kuwonjezera apo, mtengo umakhalanso wosintha nthawi zonse. .

Papepalali, ma index osiyanasiyana ndi magwiridwe antchito a chingwe cha RF akufotokozedwa mwatsatanetsatane.Ndizopindulitsa kwambiri kudziwa momwe chingwecho chimagwirira ntchito posankha msonkhano wabwino kwambiri wa RF.

Kusankha chingwe
Chingwe cha Rf coaxial chimagwiritsidwa ntchito kufalitsa mphamvu ya RF ndi ma microwave.Ndi gawo logawika lomwe kutalika kwake kwamagetsi kumayenderana ndi kutalika kwa thupi komanso kuthamanga kwa kufalikira, komwe kumakhala kosiyana kwambiri ndi ma frequency otsika.

Zingwe za Rf coaxial zitha kugawidwa m'zingwe zolimba komanso zosasunthika, zingwe zoluka, komanso zingwe zokhala ndi thovu.Mitundu yosiyanasiyana ya zingwe iyenera kusankhidwa pazogwiritsa ntchito zosiyanasiyana.Zingwe zolimba pang'ono komanso zosasinthika nthawi zambiri zimagwiritsidwa ntchito polumikizana mkati mwa zida;Pankhani yoyesa ndi kuyeza, zingwe zosinthika ziyenera kugwiritsidwa ntchito;Zingwe zokhala ndi thovu nthawi zambiri zimagwiritsidwa ntchito pamakina odyetsa antenna.

Semi-rigid chingwe
Monga momwe dzinalo likusonyezera, chingwe chamtunduwu sichimapindika mosavuta.Kondakitala wakunja amapangidwa ndi aluminiyamu kapena mkuwa chubu.Kutayikira kwa RF ndikocheperako (kuchepera -120dB) ndipo kuyankhulana komwe kumachitika pamakina ndikosavuta.

The passiv intermodulation khalidwe la chingwe ichi ndi abwino kwambiri.Ngati mukufuna kupindika mu mawonekedwe enaake, mumafunika makina opangira apadera kapena nkhungu yamanja kuti muchite.Ukadaulo wovuta woterewu pobwezera magwiridwe okhazikika, chingwe chokhazikika chogwiritsa ntchito zinthu zolimba za polytetrafluoroethylene monga sing'anga yodzaza, nkhaniyi ili ndi mawonekedwe okhazikika a kutentha, makamaka kutentha kwambiri, kumakhala ndi kukhazikika kwagawo labwino kwambiri.

Zingwe zolimba pang'ono zimawononga ndalama zambiri kuposa zingwe zosinthika pang'ono ndipo zimagwiritsidwa ntchito kwambiri pamakina osiyanasiyana a RF ndi ma microwave.

Chingwe choluka choluka
Flexible cable ndi "test grade" chingwe.Poyerekeza ndi zingwe zolimba komanso zokhazikika, mtengo wa zingwe zosinthika ndi wokwera mtengo kwambiri, chifukwa zingwe zosinthika zimapangidwira kuti ziziganizira zambiri.Chingwe chosinthika chiyenera kukhala chosavuta kupindika nthawi zambiri ndikusungabe magwiridwe antchito, chomwe ndi chofunikira kwambiri ngati chingwe choyesera.Zizindikiro zofewa komanso zabwino zamagetsi ndizotsutsana, komanso zimatsogolera ku mtengo wa chifukwa chachikulu.

Kusankhidwa kwa zigawo zosinthika za chingwe cha RF kuyenera kuganizira zinthu zosiyanasiyana nthawi imodzi, ndipo zina mwazinthu izi zimatsutsana, mwachitsanzo, chingwe cha coaxial chokhala ndi chingwe chamkati chamkati chimakhala ndi kutayika kochepa komanso kukhazikika kwa matalikidwe akamapindika kuposa chingwe cha coaxial chamitundu yambiri. , koma gawo lokhazikika la magwiridwe antchito silili bwino ngati lomaliza.Choncho, kusankha chingwe chigawo, kuwonjezera pa pafupipafupi osiyanasiyana, kuyimirira yoweyula chiŵerengero, kutayika kuika ndi zinthu zina, ayenera kuganiziranso makhalidwe makina a chingwe, malo ntchito ndi ntchito zofunika, kuwonjezera, mtengo ndi nthawi zonse. chinthu.
