1. Gushungura Bandpass
Ubusanzwe, diplexer igizwe n'amafiriti abiri ya bandpass: rimwe rigenewe umuyoboro wa transmit (Tx) (urugero, 435-455MHz) n'irindi rigenewe umuyoboro wa receive (Rx) (urugero, 460-480MHz). Aya mafiriti ya bandpass yemerera ibimenyetso biri mu byiciro byabyo bya frequency kunyuramo mu gihe bigabanya ibimenyetso hanze y'aya mafiriti. Ibi bitandukanya neza ibimenyetso byo kohereza no kwakira, bikarinda kubangamirana hagati yabyo. Urugero, diplexer ishobora kugera ku gutandukanya kwa dB 30 cyangwa hejuru hagati y'imiyoboro yayo yo hasi n'iyo hejuru, ibi bikaba bihagije ku bikorwa byinshi.

2. Igishushanyo mbonera cyo kwitandukanya cyane
Utuyungurura two mu kabari dukunze gukoreshwa muri diplexers zo mu kabari bitewe n’uko Q factor yazo iri hejuru kandi zigatoranya neza. Utu twuyungurura dutanga uburyo bwo kwitandukanya hagati y’imirongo ibiri ya frequency, bigabanya gusohoka kw’ibimenyetso biva kuri band yohereza ubutumwa bijya kuri band yo kwakira, ndetse n’ibindi. Utuyungurura two mu kabari dugabanya ibyago byo kwivanga hagati y’ibimenyetso byohereza ubutumwa n’ibyo kwakira, bigatuma sisitemu y’itumanaho ikora neza. Imiterere imwe na imwe ya diplexers, nka duplexers zo mu kabari ziterwa no kwangwa cyane, ishobora kugera ku rwego rwo hejuru cyane rwo kwitandukanya. Urugero, diplexer yo mu kabari iterwa no kwangwa cyane ishobora gutanga urugero rwo kwitandukanya rwa 80 dB cyangwa hejuru, bigakuraho neza kwivanga.

3. Guhuza Impedance
Diplexer ikoresha imiyoboro ihuza impedance kugira ngo ihuze neza impedance hagati y’imiyoboro yo kohereza n’iyakira hamwe na antene cyangwa umurongo wo kohereza. Guhuza impedance neza bigabanya reflection y’ibimenyetso n’imiraba ihagaze, bityo bigabanye ingaruka ziterwa n’ibimenyetso byagaragaye. Urugero, aho diplexer ihurira hagenewe kugera ku guhuza impedance neza, kwemeza ko impedance yinjiye ku murongo wo kohereza ari 50 ohms mu gihe igaragaza impedance nyinshi ku murongo wo kwakira.

4. Gutandukanya umwanya
Muri sisitemu z'itumanaho zihuza urubuga, diplexers zishobora guhuzwa n'ubundi buryo nko kuyobora antene, cross-polarisation, no kohereza imirasire kugira ngo habeho gukomeza gukumira interference y'ibimenyetso mu gice cyo gukwirakwiza. Urugero, gukoresha antene z'icyerekezo hamwe na diplexers bishobora kongera itandukaniro hagati y'antene zohereza n'izo kwakira, bigabanye amahirwe yo kubangamirana.

5. Imiterere mito
Utwuma duto tw’ubuhumekero dufite imiterere mito, ituma dushobora guhuzwa na antene cyangwa ibindi bice. Uku guhuza bigabanya ingano n’ubuhanga bwa sisitemu muri rusange mu gihe bigabanya ibyago byo kubangamirana. Urugero, imiterere imwe n’imwe ya diplexer ikoresha ubushobozi bwo kuyungurura mu ihuriro rusange, byoroshya imiterere ariko bigakomeza gukora neza.

Itsinda435-455MHz/460-480MHz Cavity Diplexerikoresha uburyo bwo kuyungurura imiyoboro y'itumanaho (bandpass filter), igishushanyo mbonera cy’uburyo bwo kwitandukanya cyane, guhuza impedance, gutandukanya ikirere, n’ubundi buryo bwo gukora kugira ngo icunge neza uburyo ibimenyetso bibangamira itumanaho muri sisitemu za LMR. Ibi byemeza ko ibimenyetso byohereza n’ibyakira bikora mu buryo bwihariye nta kubangamirana, bikongera ubwizerwe n’ubudahangarwa bwa sisitemu z’itumanaho.
