RF TX kōwae COFDM tuku 70Mhz 80Mhz 150Mhz 160Mhz

E tautoko ana to RF TX kōwae COFDM kaiwhakawhiti mahi ki raro 150 MHz iti iho ranei?

Inaianei kua kite matou kei te tautoko 200 MHz~2300MHz. E ai ki te whakaahuatanga o te papaaarangi TX module, kaore i te tūtohu kia mahi i raro i te 200MHz. Me tango e tatou te poari me te whakamatautau i muri mai kia kite mena ka mahi.

iVcan: Kua whakamatauhia e to maatau miihini te RF TX module COFDM transmitter pcba. Ko te auau iti rawa atu ranei ka eke ki te 70Mhz, engari ko ta maatau kaiwhiwhi te iti rawa o te 160Mhz me te 860Mhz.

Mena ka tautuhia e koe te waahanga TX ki te 70Mhz, katahi ka hiahiatia he papa-whakawhitinga ake.
Ko te iti o te auau, ka nui ake te mana tuku.
He whakakaha kaha PA iti iho i te 200 ka nui ake nga megabytes.

Kiritaki: Mo te tono o naianei, he pai te 160Mhz, na karekau he papa-whakahuri.
Ka whakamahia e matou te mana iti mai i te waahanga TX me muri i te whakamahi i a maatau ake PA, no reira ehara i to patai. Kei te hiahia tatou i te putanga o te Tx mo te -10dBm.

iVcan: I te 160MHz, ko te putanga teitei o te kōwae whakawhiti kei waenganui i -3dBm me -5dBm. Ko te tikanga, ka taea hoki te whakarite ki te -10dBm na roto i nga whakahau AT te papa tawhā ranei.

Kiritaki: -5he pai te dBm, Tena koa whakamatauria i -5 dBm putanga o Tx kōwae.

Ko te ahua ngaru ka puta te putanga-5DBM i te wa e whakamatautau ana i te waahanga TX

Kei te tautoko to RF TX Module 3.5G?

COFDM Video encoder modulator module transmitter module 3.5G me te hua whakamatautau 4G.

Ka taea e koe te tuku mai i to kōwae COFDM TX RX me te pouaka whakarewa me te whakakaha hiko o roto?

Ae, ka taea e matou te tuku atu ki a koe te huinga katoa o nga waahanga COFDM TX RX me te raima whakarewa me te whakakaha kaha (1-watt PA, 2.5-watt PA, ranei 10-watt PA kōwhiringa)r, me te antenna kaiwhakawhiti cofdm me te antenna kaiwhiwhi.
