FMUSER FUTV3627 Roo (5W) MMDS 2.5G 2.7G Aunui Whakaata Whakaata Whakaata DVB-s DVB-t Whakanui Whakawhiti

FMUSER FUTV3627 2.5G 2.7G pouaka whakaata pouaka whakaata a MMDS mamati (te punaha tohatoha ngaruiti-maha) 5W DVB-s DVB-t ka taea e te kaiwhakawhiti o roto te tautoko i te hongere kotahi, i te hongere-maha ranei. Ko te tuku hongere-kotahi te tikanga me te whakakotahi i te hiko ngaruiti hei whakakotahi i nga ngaruiti hiko-kotahi, katahi ka tukuna atu ki te antenna ma te arataki ngaru. Ma tenei ara, ka taea te whakanui ake i te mana ngaruiti ka tae ki tawhiti. Ko te hongere maha-whakawhitinga mahi whakawhiti aunui kaore e hiahiatia he whakakotahi hiko engari ka hono te puna IF ki te kaitahuri ma te whakaranu. Whai muri i te huringa auau, te tātari, me te whakakaha, ka tukuna e ia te tohu ki te antenna ma te arataki ngaru. I tenei ara, he iti te mana ngaruiti, he poto te tawhiti tuku. Ka taea e te kaiwhakawhiti MMDS te whakarato i tetahi hongere tohu me te nui o te bandwidth 200MHz. Ko te iti o te haruru o te oscillator o te rohe ka taea te whakamahi i te FUTV3627 ki te tuku tohu tairitenga me te tuku tohu mamati. Ma te whakamahi i te hangarau whakakaha raina teitei ka taea te whakanui ake i te mana tuku i te wa e whakahekehia ana te korikori kore-raina me te whakapau hiko katoa. Waihoki, ka taea e te mahi AGC te pupuri i te whakaputanga mana tonu, ka taea e te circulator te tiaki i te VSWR. Ko enei ahuatanga katoa ka whakamahia nuitia a FUTV3627 ki nga punaha haapurororaa.

painga

He iti te haruru o te oscillator rohe, e waatea ana mo te tuku tairitenga me te tuku mamati.

He iti te kohi hiko me te hoahoa superlinear ki te whakapai ake i te mana tuku, me te whakaiti i te korikori kore.

Tautokohia te mahi AGC me te whakaputanga mana totika kia pai ai te noho me te pono o te kaiwhakawhiti.

Katoa te mana o te panui o mua, ngawari te mahi.

Ko te matapihi LCD e whakaatu ana i te mana whakaputa, te mana attenuator mamati, te mana mahi AGC / MGC, me te ngaohiko.

He ngawari ki te whakauru, he ahua huatau.

Kaore he korero.
