Ma Block Up Converters (BUCs) RF Microwave Millimeter Wave mm wave

Chosinthira cha Block up (BUC) ndi purosesa ya chizindikiro yomwe imasintha ma signal otsika kukhala ma signal apamwamba (nthawi zambiri popanda kusintha zomwe zili mu chidziwitso ndi njira yosinthira ma signal), zomwe zimapangitsa kuti ikhale yoyenera pazida kapena mapulogalamu enaake.

Chosinthira cha block up, cholowetsa cha chosinthira ma frequency chimagwira ntchito nthawi imodzi pazizindikiro ziwiri, chimodzi ndi chizindikiro cholowetsa ndipo china ndi chizindikiro cha local oscillation. Njira yosinthira ma frequency ndi iyi: ma frequency a chizindikiro chotulutsa ndi apamwamba kuposa ma frequency a chizindikiro cholowetsa, ndiko kuti, ma frequency a chizindikiro cholowetsa amasunthidwa kuti akwere. Mwa kusakaniza ma frequency kuti apange zizindikiro zatsopano, kusintha ma frequency a chizindikiro kumachitika, kusintha ma signal a analog apamwamba kukhala zizindikiro za digito, potero kukwaniritsa ntchito monga kulumikizana, kuyenda, ndi kuwongolera m'magawo osiyanasiyana a ma frequency.

Kapangidwe ka chosinthira cha block up makamaka chimaphatikizapo oscillator yapafupi, chosakanizira, ndi oscillator. Chifukwa cha kuchuluka kwa ma frequency komwe kumapezeka posintha ma frequency, zofunikira zapamwamba zimayikidwa pa kukulitsa ma frequency apakati, kusefa, ndi kuchotsedwa kwa ma frequency mu wolandila, zomwe zimapangitsa kuti ndalama zambiri zolandirira zikhale zapamwamba.

Chosinthira cha Block up chimatha kukhala ndi mphamvu yayikulu kwambiri yolimbana ndi kusokoneza zithunzi ndikupeza mayankho osasunthika kwambiri pama frequency onse, omwe amagwiritsidwa ntchito kwambiri m'magawo monga kulumikizana kwa satellite, radar, ndi njira zotsutsana zamagetsi.
