RF waveguides ke lisebelisoa tse fetisang matla ho tloha sebakeng se seng ho ea ho se seng. Sebakeng sa ho khantša matla sebakeng sohle joalo ka lenakana, microwave waveguide e ka koalla matla ka tšepe e se nang letho, e fokotsang tahlehelo haholo nakong ea phetisetso ea matla. Millimeter wave waveguide e ka utloisisoa e le antenna e matla ka ho khetheha, 'me matla a ka hasoa feela ka har'a waveguide,' me a ke ke a hasana libakeng tse ling.
Phetoho ea Waveguide ke e 'ngoe ea li-waveguide, e sebelisoang haholo libakeng tse fapaneng, ho kenyeletsoa empa e sa felle feela ho likhokahano tsa microwave, litsamaiso tsa radar, li-satellite tsa puisano le lisebelisoa tsa khokahano ea radio ea microwave. Ho na le mefuta e mengata ea phetoho ea waveguide, hangata e nang le ts'ebetso e phahameng, e tloaelehileng ea leqhubu la VSWR≤1.2 ka har'a bandwidth e felletseng ea waveguide, lisebelisoa tsa mantlha tse kenyelletsang koporo, aluminium, mekhoa ea kalafo ea bokaholimo ba silevera, plating ea khauta, nickel plating, passivation, conductive oxidation, jj.

Tšobotsi e tloaelehileng ea phetoho ea waveguide ke hore likou tse peli li sebelisa mefuta e fapaneng ea waveguide bakeng sa phetoho lipakeng tsa mefuta e fapaneng ea waveguide. Ka mohlala:
1. Waveguide ho li-converter tsa microstrip: Waveguide ho li-converter tsa microstrip li sebelisoa haholo ha ho fumanoa li-circuits tse kopantsoeng tsa millimeter wave monolithic le li-circuits tsa lebasetere, hammoho le ho hokahanya ha waveguide ho li-circuits tse planar ho netefatsa phetoho e lumellanang hantle pakeng tsa mela e 'meli ea phetisetso.
2. Phetoho ho tloha ho li-waveguides tse nang le mahlakore a mabeli ho ea ho li-waveguides tse nang le mahlakore a mabeli: Li-waveguide tsa phetoho tse entsoeng ka mokhoa o nepahetseng li ka kopanya maqhubu a mabeli a mahlakoreng a mabeli ho li-waveguides tse nang le mahlakore a mabeli, ho fana ka tahlehelo e tlaase ea ho kenya le ho lumellana ho phahameng. Mofuta ona oa waveguide oa phetoho o loketse ho kengoa laboratoring le tekanyo ea kopano le lisebelisoa tsa maqhubu a mahlakore a mabeli.
3. Rectangular waveguide transition: Rectangular waveguide e fetola ka mokhoa o ts'oanang mokhoa oa TE10 ka mokhoa o tloaelehileng oa khutlonnetsepa ho mokhoa oa TE11 ka mokhoa o chitja oa waveguide. Phetoho ena e bohlokoa bakeng sa ho fetisa mats'oao ka nepo ho tloha ho leqhubu le tloaelehileng la khutlonnetsepa ho ea ho leqhubu la selikalikoe, haholo lits'ebetsong moo ho hlokehang phetoho ena ea mofuta o itseng.

QualwaveLiphetoho tsa waveguide li koahela lebelo la maqhubu ho fihla ho 220GHz, hammoho le liphetoho tse ikhethileng tsa waveguide ho latela litlhoko tsa bareki.
