Kingtone VHF BDA Bi-directional Amplifier VHF Walkie Talkie Power Amplifier
I hangaia te punaha Whakanui-a-Kingtone Bi-Directional Amplifier ki te whakaoti rapanga o te tohu waea ngoikore, he iti ake te utu atu i te taapiri i te Teihana Turanga (BTS) hou.Ko te mahi matua o te punaha RF Bi-Directional Amplifiers ko te whiwhi tohu iti-hiko mai i te BTS ma te tuku auau reo irirangi, katahi ka tukuna te tohu whakakaha ki nga waahi kaore i te tika te kapinga whatunga.Na ka whakanuia ano te tohu pūkoro ka tukuna ki te BTS ma te huarahi rereke.

UHF BDA Bi-directional amplifier uhf walkie talkie power amplifier Nga waahanga matua
1. Te wehewehe teitei hoahoa matarua katoa, ngawari ki te whakauru.
2. iti haruru ahua, tiketike whiwhi tairongo.
3. Ma te mahi ALC me te MLC hei whakarite i te mana whakaputa.
4. Ko te iti o te kaha o te kaha, te tiaki i te taiao me te whakaora kaha.
5. Hoahoa hanganga modular, ngawari ki te whakapai ake i te punaha.
6. Tātari kōhao Q teitei me te tātari ngaru oro mata SAW, teitei i waho o te aukati roopu.
7. Whakapaia te raina teitei tino matatau o te ao, he iti te whakakorikori hiko LDMOS intermodulation.
8. Whakamahia te PLL mamati matatau, TCXO, hangarau OCXO, te pumau o te auau me te tino tika.
9. He tino pai te mahi aroturuki whatunga mamao me te rohe.
10. He mahi hoahoa parewai mo nga huarere katoa o roto me waho.

Hei whakawhänui i te kapi tohu mo te whakaki i te waahi matapo tohu e ngoikore ana te tohu
kore wātea ranei.
Waho: Taunga rererangi, Rohe Tapoi, Papa korowha, Tunnels, wheketere, Takiwa keri, kainga etc.
Roto: Hotera, Whare Whakaaturanga, Raro, Hokohoko
Nga Toa, Nga Tari, Te Taapaki Lot etc.
Ko te nuinga e pa ana ki nga keehi penei:
Ka kitea e te kaitahuri he waahi whakaurunga ka taea te whiwhi tohu BTS parakore i te taumata kaha na te mea ko te Taumata Rx i te waahi tukurua kia neke ake i te ‐70dBm;
A ka taea e koe te whakatutuki i nga whakaritenga o te wehenga antenna kia kore ai e whakapouri i a koe ano.
