800MHz bandpass lua kānana
800MHz bandpass lua kānana,
Mea hana o RF kānana,
wehewehe
ʻO GSM Bandpass Cavity kānana e hana ana mai ka 890-915MHz me ka poho haʻahaʻa
ʻO JX-CF1-890M915M-S25 ʻO ka kānana ʻo Bandpass i uhi ʻia mai ka 890-915MHz me ka band pass o 25MHz. Hōʻike ia i ka poho haʻahaʻa haʻahaʻa o 15dB, ka poho hoʻokomo ʻaʻole ʻoi aku ma mua o 2dB, a hana ma lalo o ka mana o 50W. Hana ʻia kēia kānana bandpass cavity no ke ʻano FDD, ana ʻia ʻo 100mm x 65mm x 36mm wale nō me nā mea hoʻohui SMA.
Hoʻohana ʻia no ka ʻōnaehana GSM, hoʻokō paʻa a hilinaʻi ʻo bandpass cavity kānana JX-CF1-890M915M-S25 e like me ka manaʻo. Hiki ke hoʻopilikino ʻia kēia mau kānana GSM bandpass cavity e Jingxin no nā noi like ʻole. E like me ka mea i hoʻohiki ʻia, loaʻa nā ʻāpana passive RF āpau mai Jingxin i 3 mau makahiki.
ʻĀpana
| ʻĀpana | Hōʻike |
| Laulā pinepine | 890-915MHz |
| Hoʻihoʻi poho | ≥15dB |
| poho hookomo | ≤2.0dB |
| Hōʻole | ≥30dB @ 869-885MHz |
| Ka mana maʻamau | 50W |
| Ka hoʻopalekana | 50Ω |
Nā ʻāpana RF Passive maʻamau
Ma ke ʻano he mea hana i nā ʻāpana passive RF, hiki iā Jingxin 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 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.
