FMUSER FUTV3627 Indoor (5W) MMDS 2.5G 2.7G Broadband TV Broadcast DVB-s DVB-t Transmitter Amplifier

FMUSER FUTV3627 2.5G 2.7G TV yowulutsa ma digito MMDS (njira yogawa ma microwave yama microwave) 5W DVB-s DVB-t transmitter ya m'nyumba imatha kuthandizira kufalitsa kanjira kamodzi kapena kanjira zambiri. Kutumiza kwa njira imodzi nthawi zambiri kumafuna chophatikizira cha mphamvu ya microwave kuti aphatikize ma microwave anjira imodzi, kenako ndikuwatumiza ku mlongoti kudzera pa waveguide. Mwanjira iyi, mphamvu ya microwave imatha kukulitsidwa ndikufikira mtunda wautali. Ntchito yotumizira ma mayendedwe ophatikizika ndi njira zambiri sifunikira chophatikizira chamagetsi koma imalumikiza gwero la IF ku transmitter kudzera mu chosakanizira. Pambuyo pa kutembenuka kwafupipafupi, kusefa, ndi kukulitsa, imatumiza chizindikiro ku mlongoti kudzera pa waveguide. Mwanjira iyi, mphamvu ya microwave ndiyotsika ndipo mtunda wotumizira ndi waufupi. Transmitter ya MMDS imatha kupereka njira yolumikizira yokhala ndi bandwidth yayikulu ya 200MHz. Phokoso lotsika la oscillator wamba limalola FUTV3627 kuti igwiritsidwe ntchito potumiza ma analogi ndi digito. Kugwiritsa ntchito ukadaulo wapamwamba kwambiri wokulitsa liniya kumatha kukulitsa mphamvu zotumizira ndikuchepetsa kupotoza kopanda mzere komanso kugwiritsa ntchito mphamvu zonse. Momwemonso, ntchito ya AGC imatha kukhalabe ndi mphamvu zotulutsa nthawi zonse, ndipo chozungulira chingapereke chitetezo cha VSWR. Zonsezi zimapangitsa FUTV3627 kugwiritsidwa ntchito kwambiri pamakina owulutsa.

ubwino

Phokoso la gawo lotsika la oscillator, lomwe limapezeka pamayendedwe a analogi ndi digito.

Kugwiritsa ntchito mphamvu zochepa komanso mapangidwe apamwamba kwambiri kuti apititse patsogolo mphamvu zotumizira, ndikuchepetsa kupotoza kosasinthika.

Thandizani ntchito ya AGC yokhala ndi mphamvu zokhazikika kuti ma transmitter azikhala okhazikika komanso odalirika.

Full digito kutsogolo gulu ulamuliro, ntchito yosavuta.

Zenera la LCD lowonetsa mphamvu zotulutsa, mawonekedwe a digito, mawonekedwe ogwirira ntchito a AGC/MGC, ndi magetsi.

Easy kukhazikitsa, kaso maonekedwe.

Palibe chidziwitso.
