Cov Lus Qhia
Txheej txheem cej luam
Qhov no module belongs rau UHF Cov khoom siv xov tooj cua sib txuas lus hauv cov zaus band, uas tuaj yeem xa suab thiab yees duab tsis pub dhau qhov txwv. Tsim los rau kev siv hluav taws xob tsawg, integrated VCO, PLL, thiab AM broadband video demodulation, Lub suab cab kuj ua rau lub module me dua; nws txais ib lub pob me me ib zaug, uas yooj yim rau cov neeg siv los ua cov ntawv thov me me.
Daim ntawv thov ntawm qhov module no tsuas yog xav tau yooj yim txuas lub zog hluav taws xob, audio kab, thiab video cable, thiab txuas tus kav hlau txais xov kom siv ntau yam khoom siv hluav taws xob uas txhawb nqa analog TV txais tos, suav nrog cov xov tooj ntawm tes, TVs, laptops, MP4, thiab cov duab digital.
