I-BTF Testing Lab Radio frequency (RF) isingeniso Isithombe Esifakiwe

Isethulo se-BTF Test Lab Radio frequency (RF).

incazelo emfushane:

Ifrikhwensi yomsakazo ibizwa nge-RF, ifrikhwensi yomsakazo ingeye-RF yamanje, iwuhlobo lwe-AC eshintshashintshayo igagasi logesi ngamafuphi. Ilebhu yokuhlola ye-BTF inelabhorethri yefrikhwensi yomsakazo ephelele. I-alternating current eshintsha izikhathi ezingaphansi kwezingu-1000 ngesekhondi ibizwa ngokuthi i-low-frequency current, kanti i-frequency current enkulu kunezikhathi ezingu-10,000 ibizwa ngokuthi i-high-frequency current, kanti ifrikhwensi yomsakazo injalo imvamisa ephezulu. Uhlelo lukamabonakude wekhebula lisebenzisa imodi yokudlulisa amaza omsakazo.

Ku-electronics, amandla kagesi ageleza ku-conductor futhi amafomu kazibuthe azungezile. I-alternating current idlula ku-conductor, bese kwakheka inkambu ye-electromagnetic eshintshanayo eduze kwe-conductor, ebizwa ngokuthi i-electromagnetic wave.

Lapho i-electromagnetic wave frequency ingaphansi kuka-100kHz, igagasi kazibuthe lizomuncwa phezulu futhi alikwazi ukwenza ukudluliselwa okuphumelelayo, kodwa lapho i-electromagnetic wave frequency ingaphezu kuka-100kHz, igagasi kazibuthe lingasabalala emoyeni futhi libonakale i-ionosphere emaphethelweni angaphandle omkhathi, enza ikhono lokudlulisa ibanga elide, sibiza igagasi logesi elihamba ngamagagasi aphezulu elinamandla okudluliswa kwebanga elide frequency yomsakazo, isifinyezo sesiNgisi: RF
