ʻO Kina kiʻekiʻe kiʻekiʻe i hana ʻia 136-174MHz VHF Band Selective Bi-directional Amplifiers (BDA)
1. High kaʻawale piha duplex hoʻolālā, maʻalahi e hoʻouka.
2. Haʻahaʻa leo huahelu, kiʻekiʻe loaʻa sensitivity.
3. Me ka hana ALC a me MLC e hōʻoia i ka mana puka paʻa.
4. Ka hoʻohana ʻana i ka mana haʻahaʻa, ka mālama ʻana i ke kaiapuni a me ka mālama ʻana i ka ikehu.
5. Hoʻolālā hoʻolālā modular, maʻalahi e hoʻonui i ka ʻōnaehana.
6. Kiekie Q cavity kānana a me SAW surface acoustic hawewe kānana, kiʻekiʻe ma waho o ka band rejection.
7. Hoʻohana i ka laina kiʻekiʻe kiʻekiʻe loa o ka honua, haʻahaʻa intermodulation LDMOS mana amplifier.
8. E hoʻohana i ka PLL kikohoʻe kikohoʻe kiʻekiʻe, TCXO, ʻenehana OCXO, paʻa pinepine a me ka pololei kiʻekiʻe.
9. Pono ka hana nānā pūnaewele mamao a kūloko.
10. He hana hoʻolālā wai ʻole no nā wā āpau i loko a me waho.
ʻElua Kuhina Hoʻolālā o BDA no ke koho o ka mea kūʻai aku
He aha ka Bi-Directional Amplifier BDA?
Hoʻohana ʻia kahi Bi-Directional Amplifier (a i ʻole BDA) no ka hoʻonui ʻana i ka lekiō ma ka pūnaewele i nā hōʻailona RF i nā hale, nā tunnel a i ʻole nā wahi i uhi ʻia.He mau ʻāpana kā BDA: ʻO kahi antena hāʻawi e hōʻiliʻili i ka hōʻailona mai ka hale i kahi ikaika a hāʻawi iā ia i ka BDA no ka hoʻonui ʻana.Hāʻawi ʻia ka hōʻailona i hoʻonui ʻia i hoʻokahi a ʻoi aʻe paha nā antenna hoʻolaha ma nā wahi ʻino ka uhi.Loaʻa nā BDA ma nā pūna kikoʻī he nui: VHF, UHF, 700MHz, 800MHz, a me cellular/LTE etc.
He hōʻailona ka hapa nui o nā wahi, ʻaʻole wale ma nā wahi āpau i koi ʻia ma ka pūnaewele.No ka laʻana, loaʻa paha i kahi hōkele ka hōʻailona ma nā papahele o luna, akā ʻaʻole i ka paka.No ka hāʻawi ʻana i ka hōʻailona i loko o ka parkade, e hoʻokomo mākou i kahi antenna e kiʻi i ka hōʻailona mai ka pūnaewele kelepona a i ʻole ka mea hana hou mai nā wahi hana, hānai iā ia i ka amplifier a laila hele i nā antenna hou aʻe e kokoke ana i nā wahi me ka uhi hemahema.uhi.
