Popanda fyuluta mu RF kutsogolo, zomwe zimalandira zidzachepetsedwa kwambiri. Kodi kuchotsera ndi kwakukulu bwanji? Mwambiri, ndi antennasi yabwino, mtunda udzakhala wophweka kawiri. Komanso, nyemba za lendna, zoyipa kwambiri. Ndichoncho chifukwa chiyani? Chifukwa chakuti kumwamba kumadzazidwa ndi zizindikiro zambiri, zizindikirozi zikulepheretsa kutsogolo chubu. Popeza fyuluta yakutsogolo ndiyofunikira kwambiri, momwe mungapangire kupanga flow-kumapeto? RF Makampani Ophunzira Mphunzitsi Kukuphunzitsani! Komabe, fyuluta yotsiriza ya 435mhz siosavuta kuwonjezera. Tiyeni tiyambitse kusanthula
Ili ndi seti ya chebyshev band-toptar yokhala ndi mphamvu yayikulu yolumikizana ndi ma 435mhz. Chifukwa cha kugwiritsa ntchito kwa chip yopezeka pa malonda (omwe ali ndi mtengo wa Q mpaka 70), kutayika kwa -ku kuli kokulirapo, kufikira -1DB, ndi mawonekedwe enawo ndikuwonetsa kukhala mafunde. Chifukwa chake, kuzindikira kwa wolandirayo kumakhudzidwa kwambiri, chifukwa kukhudzidwa kwa wolandirayo kumakhudzana mwachindunji ndi katswiriyu ndi wabwino, monganso luso la kuchuluka kwa ma 0DE. Chifukwa chake sizosowa kuwona imodzi yomwe imagwiritsidwa ntchito ngati iyi. Onaninso chithunzichi kachiwiri:
Sungani magawo enanso, indoctor imasinthidwa ndi colul yabwino kwambiri yopanda kanthu, ngakhale voliyumu ndi yayikulu, koma kutayika komwe kumakhala --5, komwe kumakhala kovuta, koma ndizovuta kwambiri. Chifukwa: Mphamvu yophatikizira pamtunda ndi 0,2p, ndi mphamvu ya mphamvuyi siyophweka kugula, kotero mutha kujambula katswiri pa PCB, yomwe imabweretsa vuto 1. Ngakhale indoctor ya 12nh siabwino kwambiri kumphepo, ndipo iyenera kukhala yopanda tanthauzo komanso yopanda kanthu, ndipo siabwino kudziwa ngati palibe chokwanira. Chizindikiro chake chikadali chokulirapo, magawo a mavactors amenewo ndiovuta kwambiri, ndipo kusintha pang'ono kumakhudza magwiridwe antchito. Nanga mungatani ngati mungathe kupitiliza kuwonjezera mtengo wa Insuctor, ndipo pali njira yopitirizira kuchepetsa mphamvu yophatikizira? Kenako sinthani bandwidth pang'ono. Zinthu zitha kukhala motere:
Kufunika kwa chiwonetsero cha chiwonetserochi mwadzidzidzi kumakhala 1600, ndipo chifundo chimakhala chokulirapo, chithunzicho chimakhala chokongola kwambiri, zosefera za wolandirayo ndi zizindikiro, mwadzidzidzi amakoka mtunda wautali. Kuchita bwino, koma kukula kwake ndi zofananira kwambiri
Kupanga kwazithunzi zozungulira za zosefera kuzungulira kumeneku, anthu ochepa amakhala ochepera ku China, ndipo pulogalamuyi imatha kuphatikizidwa bwino. Choyamba, chithunzi cham'mbuyomu chimayambitsa zosefera zenizeni za 435mhz mafoni am'ma foni. M'malo mwake, zosefera bwino ziyenera kumangiriridwa kwambiri, timapanga 2-zapamwamba komanso zosefera 4 za makina oyesa awa.
