Duplexer/Diplexer ea Moralo o Ikhethileng bakeng sa Litharollo tsa RF

Tlhaloso ea Sehlahisoa

Diplexers/Duplexers tsa rona tse entsoeng ka mokhoa o ikhethileng ke li-filter tsa RF tse hlokahalang haholo lits'ebetsong tsa maqhubu a phahameng 'me li etselitsoe ho fihlela litlhoko tse fapaneng tsa puisano. Mefuta ea maqhubu e akaretsa 10MHz ho isa ho 67.5GHz, e netefatsang ts'ebetso e ntle maemong a mangata a ts'ebeliso. Ebang ke puisanong ea waelese, puisanong ea sathelaete kapa masimong a mang a ts'ebetso ea matšoao a maqhubu a phahameng, lihlahisoa tsa rona li ka fana ka litharollo tse tšepahalang.

Mosebetsi o ka sehloohong oa duplexer ke ho aba matšoao ho tloha koung e le 'ngoe ho ea litseleng tse ngata ho netefatsa hore phetiso ea matšoao e sebetsa hantle. Duplexer tsa rona li na le tahlehelo e tlase ea ho kenya, ho itšehla thajana ho hoholo le bokhoni bo phahameng ba ho sebetsana le matla, e leng se ka fokotsang tahlehelo ea matšoao ka katleho le ho ntlafatsa ts'ebetso eohle ea sistimi. Litšobotsi tse tlase tsa PIM (intermodulation distortion) li etsa hore lihlahisoa tsa rona li sebetse hantle lits'ebetsong tse matla haholo, ho netefatsa ho hlaka le botsitso ba matšoao.

Mabapi le moralo, li-duplexer tsa rona li sebelisa mefuta e fapaneng ea mahlale a tsoetseng pele, ho kenyeletsoa cavity, LC circuit, ceramic, dielectric, microstrip, spiral le waveguide, jj. Motsoako oa mahlale ana o lumella lihlahisoa tsa rona ho tenyetseha haholo ka boholo, boima le ts'ebetso. Re boetse re fana ka lits'ebeletso tsa moralo o ikhethileng ho fihlela litlhoko tse ikhethileng tsa bareki ba rona mabapi le boholo le litlhoko tsa tekheniki, ho netefatsa hore duplexer e 'ngoe le e 'ngoe e loketse tikoloho ea eona ea ts'ebeliso.

Ho phaella moo, di-duplexer tsa rona di hanela ho thothomela le ho tshoha ka sebopeho, e leng se di dumellang ho sebetsa ka botshepehi dibakeng tse thata. Ka nako e ts'oanang, moralo o sa keneleng metsi o boetse o etsa hore dihlahiswa tsa rona di lokele dibaka tsa kantle le tse ding tse mongobo, e leng se eketsang tshebediso ya tsona haholo.

Ka bokhutšoanyane, li-duplexer/li-divider tse entsoeng ka mokhoa o ikhethileng tsa Apex ha li sebetse hantle feela ts'ebetsong empa hape li fihlela litlhoko tse fapaneng tsa litsamaiso tsa puisano tsa sejoale-joale mabapi le ts'epo le ho tenyetseha. Hore na o hloka tharollo ea RF e sebetsang hantle kapa moralo o ikhethileng o ikhethileng, re ka u fa khetho e ntle ka ho fetisisa.
