Hiki ke kānana no VHF 152-174MHz
ʻO kāna kānana kūpono no VHF 152-174MHz,
Mea hana o RF kānana,
wehewehe
VHF Tunable kānana e hana ana mai 152-174MHz me nā mea hoʻohui N
ʻO ka kānana VHF JX-SF1-152174-215N kahi ʻano kānana tunable no ka VHF e hana ana mai 152-174MHz me ka bandwidth o 5-15MHz. pohō ma lalo o 0.5-2.2dB i nā bandwidths like ʻole, hoʻihoʻi i ka poho ma luna o 20dB, a me ka hōʻole kiʻekiʻe pū kekahi.
Hoʻolālā ʻia kēlā ʻano kānana cavity no ka hoʻopaʻa ʻana i kona alapine e like me ke alapine tunable, no laila hiki ke hoʻohana nui ʻia no nā hoʻonā VHF. E like me ka mea hoʻolālā kānana RF, hiki ke hoʻonohonoho pono ʻia nā kānana ʻoi aku ka maikaʻi. E like me ka mea i hoʻohiki ʻia, loaʻa nā ʻāpana passive RF āpau mai Jingxin i 3 mau makahiki.

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.
