Kuopsa kwa amplifier ya chizindikiro cha foni yam'manja ndi zinthu zomwe zimafunika kusamalidwa

Zokulitsa mawu a foni yam'manjaIwo okha savulazidwa mwachindunji. Ndi zipangizo zamagetsi zomwe zimapangidwa kuti ziwonjezere zizindikiro za mafoni, zomwe nthawi zambiri zimakhala ndi antenna yakunja, amplifier, ndi antenna yamkati yolumikizidwa ndi zingwe. Cholinga cha zipangizozi ndikutenga zizindikiro zofooka ndikuzikulitsa kuti zipereke kulumikizana kwabwino kwa mafoni komanso kufalikira kwa zizindikiro.

Komabe, pali mfundo zingapo zofunika kuziganizira mukamagwiritsa ntchito ma amplifiers a ma signal a m'manja:

Zalamulo: Mukagwiritsa ntchitoamplifier ya chizindikiro cha mafoni, muyenera kuonetsetsa kuti ndi lamulo komanso kuti zikutsatira malamulo am'deralo. Madera ena akhoza kukhala ndi zoletsa kapena zoletsa kugwiritsa ntchito ma amplifiers pa ma frequency band enaake, chifukwa angasokoneze magwiridwe antchito a zida zina zopanda zingwe kapena malo oyambira.

Kukhazikitsa ndi kugwiritsa ntchito molakwika: Kukhazikitsa molakwika kapena kugwiritsa ntchito molakwika amplifier ya chizindikiro kungayambitse kusokoneza ndi mavuto. Mwachitsanzo, ngati kutalika kwa chingwe pakati pa ma antenna amkati ndi akunja kuli kotalika kwambiri kapena ngati mawaya sali olondola, kungayambitse kutayika kwa chizindikiro kapena mavuto okhudzana ndi mayankho.

Mphamvu yamagetsi:Zokulitsa mawu a foni yam'manjaamafuna magetsi, zomwe zikutanthauza kuti amapanga mphamvu yamagetsi yochuluka. Komabe, poyerekeza ndi mafoni am'manja kapena zida zina zolumikizirana zopanda zingwe, mphamvu yamagetsi ya ma amplifiers nthawi zambiri imakhala yotsika chifukwa nthawi zambiri imapangidwira kugwiritsidwa ntchito m'nyumba m'malo moyandikira thupi la munthu. Komabe, ngati muli ndi vuto la mphamvu yamagetsi kapena muli ndi nkhawa zaumoyo, mutha kutenga njira zoyenera zodzitetezera monga kupewa amplifier kapena kusankha zida zomwe zili ndi mphamvu yamagetsi yocheperako.

Kusokoneza kwa zizindikiro: Ngakhale cholinga chama amplifiers a chizindikiro cha mafoniKuti apereke zizindikiro zolimba, kuyika kapena kugwiritsa ntchito molakwika kungayambitse kusokoneza kwa zizindikiro. Mwachitsanzo, ngati amplifier igwira ndikukulitsa zizindikiro zosokoneza kuchokera kuzipangizo zapafupi, izi zitha kubweretsa kuchepa kwa khalidwe la kulumikizana kapena kusokoneza.

Mwachidule, ma amplifiers a ma signal a m'manja omwe apezeka mwalamulo komanso oyikidwa bwino nthawi zambiri sawononga mwachindunji. Komabe, ndikofunikira kutsatira malamulo am'deralo, kutsatira malangizo ndi malangizo a wopanga, ndikuwonetsetsa kuti ayikidwa bwino komanso akugwiritsidwa ntchito. Ngati muli ndi nkhawa kapena mafunso, ndi bwino kufunsa akatswiri kapena akuluakulu oyenerera kuti akupatseni malangizo ndi chitsogozo cholondola.
