ʻO LoraWan 868MHz Bandpass kānana

Hoʻohana nui ʻia ʻo 868 MHz-band no nā thermostats, nā ʻōnaehana ahi, nā ʻōnaehana burglar, kūlana, a me nā DIN-transceivers, ʻo LoraWan pūnaewele a i ʻole nā ​​ʻōnaehana IoT, nā ʻenehana sensor uila ...

No ka hoʻokō ʻana i ke koi o ke kūʻai aku, ua hoʻolālā kūikawā kā mākou hui R&D i 2 mau ʻano kānana bandpass cavity e hana ana mai ke alapine ākea 864-872MHz, nona nā koho o loko a i waho paha. ʻO ka kānana bandpass no ka hoʻonā i loko he liʻiliʻi liʻiliʻi i pena ʻia i ke kala keʻokeʻo, hiki ke loaʻa i nā kala ʻē aʻe no ke koho ʻana, ʻo ke ʻano kikoʻī e like me kēia, ka hōʻole kiʻekiʻe a me ka nalowale hoʻokomo haʻahaʻa, i hoʻāʻo ʻia e like me ka spec, ke kumukūʻai. he hoʻokūkū nui nō hoʻi. No ka 868MHz hoʻonā pūnaewele i loko, ʻo kēia kānana lua ka mea maikaʻi loa no ka ʻike.

Me ka wai ʻole IP67, ua hoʻolālā piha ʻia ka kānana cavity ma lalo nei no ka lawe ʻana i ke kaiapuni hana paʻakikī, i pena ʻia i ke kala hina i ka leo liʻiliʻi. ʻO kona ʻāpana e like me ka mea i luna ma waho o ka hana ʻana ma waho. Ke hana maikaʻi nei kēia mau kānana me ke ola lōʻihi, hiki ke hana pū me ka antenna no ka ʻoihana helium.

Hiki iā Jingxin ke hana i nā kānana RF ke hoʻolālā i nā ʻano like ʻole e like me nā noi a nā mea kūʻai aku.

ʻO 3 mau ʻanuʻu wale nō e hoʻoponopono ai i kāu pilikia o ka RF Passive Component

1. Ke wehewehe ʻana i ka ʻāpana e ʻoe.

2. Hāʻawi i ka noi no ka hōʻoia ʻana e Jingxin.

3. Ka hana ʻana i ka prototype no ka hoʻāʻo ʻana e Jingxin.

Hoʻokipa ʻia nā kikoʻī hou aku e kūkākūkā me mākou.
