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

सामग्रीको तालिका

अवलोकन

This module belongs to UHF Radio communication equipment in the frequency band, which can transmit audio and video within a limited range. Designed for low power consumption, integrated VCO, PLL, and AM broadband video demodulation, The audio carrier frequency makes the module smaller; it adopts a small single-board package, which is convenient for users to miniaturize applications.

The application of this module only needs to simply connect the power supply, audio cable, and video cable, and connect the antenna to use a variety of electronic equipment terminals that support analog TV reception, मोबाइल फोन सहित, TVs, laptops, MP4, and digital photos.

सोधिने प्रश्न

Can you make this UHF wireless video transmitter with a 10-watt amplifier?

Now we don’t have an analog video transmitter with a 10-watt PA. It is not simply to add a 10-watt PA to our existing analog video transmitter. It needs to be redesigned and re-produced.

The engineer suggests that you test our normal analog video transmitter first. After you use it, tell us what should be improved and we can add them to the new sample with a 10-watt PA. So would you like to test an existing sample (no PA) first?
