He aha ke ʻano o ka cavity diplexer?
ʻO ka cavity diplexer kahi mea hana passive e hiki ai i ka hoʻouna like ʻana a me ka loaʻa ʻana o nā hōʻailona ma luna o kahi antena hoʻokahi ma ka hoʻokaʻawale ʻana i nā kaha alapine i koho ʻia. ʻO kā mākou 891-903mhz / 936-948mhz cavity diplexer ua hana ʻia e hāʻawi i kahi kaʻawale kūʻokoʻa ma waena o nā hui rx (891-903mhz) a me tx (936-948mhz).

Nā hiʻohiʻona ʻenehana nui
ua hoʻolālā ʻia kā mākou cavity diplexer e hoʻokō i nā koi koi o nā ʻōnaehana kamaʻilio hou:
• rx kikowaena alapinepine: 897mhz ± 1mhz
• tx kikowaena alapinepine: 942mhz ±1mhz
• poho hoʻokomo: ≤1db ma nā pūʻulu ʻelua
• ka lākiō hawewe kū uila (vswr): ≤1.3:1
• hōʻole: ≥65db ma waena o nā hui
• impedance: 50 ohms
• nā mea hoʻohui: sma-female ma nā awa a pau
• ka mana hana: 10w i mua, 2w i hope
• ka mahana hana: -20°c i +65°c
• mea waiwai: aluminika me ka pena ʻeleʻele

He aha ka mea e hoʻokaʻawale ai i kā mākou cavity diplexer?
• hana pololei: ʻo kā mākou hale hana 20 makahiki ma chengdu e hana i kēlā me kēia diplexer me ka mana koʻikoʻi.
• hoʻoponopono i hana ʻia: hāʻawi mākou i nā hoʻololi alapine, nā hoʻololi hoʻohui, a me nā pale kau maʻamau.
• ka hoʻouna wikiwiki: moku nā laʻana i loko o nā hola 48, me nā kauoha maʻamau i hoʻokō ʻia i nā lā 21.
• kākoʻo ʻoihana: hāʻawi kā mākou hui i ke kōkua ʻenehana mai ka hoʻolālā a hiki i ka hoʻokō.

Pehea e pōmaikaʻi ai kēia i kāu ʻōnaehana?
kōkua ka cavity diplexer i ka hoʻohana ʻana i ka antenna a pale i ka hoʻopili ʻana i ka hōʻailona ma:
• gsm-r a me ke alahao
• pmr a me nā pūnaewele palekana lehulehu
• nā noi iot a me m2m
e kelepona mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou891-903mhz/936-948mhz lua diplexera pehea e hiki ai iā ia ke hoʻonui i kāu ʻōnaehana kamaʻilio.
