1. Tātari Bandpass
Ko te tikanga, e rua ngā tātari whakawhiti-roopu o te diplexer: tētahi mō te roopu auau tuku (Tx) (hei tauira, 435-455MHz) me tētahi atu mō te roopu auau whiwhi (Rx) (hei tauira, 460-480MHz). Mā ēnei tātari whakawhiti-roopu ka taea e ngā tohu i roto i ō rātou awhe auau te haere mā roto, me te whakaiti i ngā tohu i waho o ēnei roopu. Mā tēnei ka wehea ngā tohu tuku me ngā tohu whiwhi, ka ārai i te pokanoa i waenganui i a rātou. Hei tauira, ka taea e te diplexer te whakatutuki i te wehenga o te 30 dB, neke atu rānei i waenganui i ōna tauranga iti me te teitei, he rawaka tēnei mō te nuinga o ngā tono.

2. Hoahoa Wehewehenga Teitei
He mea noa te whakamahi i ngā tātari poka i roto i ngā pūwero poka nā te mea he nui te Q tauwehe me te tino whiriwhiri. Ka whakaratohia e ēnei tātari he wehenga teitei i waenga i ngā roopu auau e rua, ka whakaiti i te turuturu tohu mai i te roopu tuku ki te roopu whiwhi, me te rereke. Ka whakaitihia e te wehenga teitei te mōrearea o te pokanoa i waenga i ngā tohu tuku me te whiwhi, ka whakarite kia pumau te mahi a te pūnaha whakawhitiwhiti kōrero. Ka taea e ētahi hoahoa pūwero poka, pērā i ngā pūwero poka whakakore-teitei, te whakatutuki i ngā taumata wehenga tino teitei. Hei tauira, ka taea e te pūwero poka whakakore-teitei te whakarato i ngā taumata wehenga o te 80 dB, neke atu rānei, ka pehi pai i te pokanoa.

3. Te Whakataurite Āraitanga
Kei roto i te diplexer ngā whatunga taurite aukati hei whakarite i te taurite aukati pai i waenga i ngā hongere tuku me ngā hongere whiwhi me te pūihi, te raina tuku rānei. Mā te taurite aukati tika ka whakaitihia ngā whakaata tohu me ngā ngaru tū, ā, ka whakaitihia te pokanoa i puta mai i ngā tohu whakaata. Hei tauira, kua hangaia te hononga noa o te diplexer kia tutuki ai te taurite aukati pai rawa atu, kia 50 ohms te aukati tāuru i te auau tuku, me te whakaatu i te aukati teitei i te auau whiwhi.

4. Te Wehewehenga Wāhi
I roto i ngā pūnaha whakawhitiwhiti kōrero pae-tahi, ka taea te whakakotahi i ngā diplexer me ētahi atu tikanga pēnei i te ahunga o te pūihi, te whakawhiti-polarization, me te tuku hihi hei whakatutuki i te pehi atu i te pokanoa tohu i roto i te rohe horapa. Hei tauira, mā te whakamahi i ngā pūihi ahunga me ngā diplexer ka taea te whakanui ake i te wehenga i waenga i ngā pūihi tuku me ngā pūihi whiwhi, ka whakaiti i te tūponotanga o te pokanoa tetahi ki tetahi.

5. Hanganga Kiato
He hanganga kiato ngā pūwero rua, e āhei ai te whakauru atu ki ngā pūihi, ki ētahi atu wāhanga rānei. Mā tēnei whakaurunga ka whakaitihia te rahi me te uaua o te pūnaha whānui, me te whakaiti hoki i ngā tūponotanga pokanoa. Hei tauira, ko ētahi hoahoa pūwero rua ka whakauru i ngā āheinga tātari ki roto i te hononga noa, ka whakangawari i te hanganga me te pupuri tonu i te mahi teitei.

Te435-455MHz/460-480MHz Pūwhakawhiti KōhaoKa whakamahia te tātari bandpass, te hoahoa wehewehe teitei, te taurite aukati, te wehewehe wāhi, me ētahi atu hangarau hei whakahaere tika i te pokanoa tohu i roto i ngā pūnaha LMR. Mā tēnei ka whakarite kia mahi motuhake ngā tohu tuku me te tohu whiwhi me te kore he pokanoa tetahi ki tetahi, ka whakapai ake i te pono me te pumau o ngā pūnaha whakawhitiwhiti kōrero.
