He aha te diplexer poka?
He taputapu kore mahi te cavity diplexer e āhei ai te tuku me te whiwhi tohu i te wā kotahi mā te wehewehe i ngā roopu auau kua tohua. Kua hangaia tā mātou cavity diplexer 891-903mhz/936-948mhz hei whakarato i te wehenga motuhake i waenga i ngā roopu rx (891-903mhz) me te tx (936-948mhz).

Ngā āhuatanga hangarau matua
Kua hangaia tā mātou pūrua rua hei whakatutuki i ngā whakaritenga nui o ngā pūnaha whakawhitiwhiti kōrero hou:
• auau pokapū rx: 897mhz ±1mhz
• auau pokapū tx: 942mhz ±1mhz
• ngaronga whakaurunga: ≤1db puta noa i ngā roopu e rua
• ōwehenga ngaru tū ngaohiko (vswr): ≤1.3:1
• whakakorenga: ≥65db i waenga i ngā roopu
• ārai: 50 ohms
• hononga: sma-wahine i ngā tauranga katoa
• mana whakahaere: 10w whakamua, 2w whakamuri
• pāmahana whakahaere: -20°c ki te +65°c
• rauemi: konumohe me te paninga peita pango

He aha te mea e wehewehe ai i tā mātou diplexer poka?
• te hanga tino tika: e hanga ana tā mātou wheketere 20-tau i Chengdu i ia diplexer me te mana whakahaere kounga tino pakari.
• whakaritenga kua whakaritea kia rite ki te tono: ka tukuna e mātou ngā whakatikatika auau, ngā huringa hononga, me ngā whāriki whakairi ritenga.
• tuku tere: ka tukuna ngā tauira i roto i ngā hāora 48, ā, ka tutuki ngā ota paerewa i roto i ngā rā 21.
• tautoko ngaio: ka whakaratohia e tā mātou tīma he āwhina hangarau mai i te hoahoa ki te whakatinanatanga.

He aha ngā painga o tēnei ki tō pūnaha?
Ka āwhina te cavity diplexer ki te arotau i te whakamahinga o te pūihi me te ārai i te pokanoa o te tohu i roto i:
• GSM-R me ngā whakawhitiwhitinga rerewē
• pmr me ngā whatunga haumaru tūmatanui
• ngā tono iot me te m2m
