FPV Analog Video Transmitter CVBS audio video module sender 400-900MHz UHF vcan1904

Cov Txheej Txheem

Overview

Qhov module belongs rau UHF Xov tooj cua sib txuas lus hauv lub frequency qhab, Uas yuav transmit audio thiab yees duab nyob rau hauv ib chav txwv ntau yam. Tsim rau cov hwjchim uas tsis muaj hwj huam noj, integrated VCO, PLL, thiab AM broadband yees duab demodulation, Lub suab muaj zaus ua rau lub module me me; Nws adopts ib zaug xwb-board pob, Uas yog convenient rau cov neeg siv miniaturize daim ntawv thov.

Daim ntawv thov no module tsuas yuav tsum tau txuas nrog cov hwjchim mov, audio cable, thiab yees duab cable, Thiab txuas nrog tus antenna siv ntau yam khoom siv khoom davhlau ya nyob twg uas txhawb analog TV txais tos, xws li txawb tes txawb, TVs, laptops, MP4, thiab cov duab.
