Wireless Microphone Chip - U1T32A

The U1T32A is a transmitter chip for wireless audio transmission, paired with a wireless receiver chip to achieve high-quality wireless audio transmission. The RF operating range is UHF 500M~980MHz. Due to the integrated MCU core and necessary peripherals, the single-chip integration is high and cost-effective. Suitable for wireless karaoke systems, wireless audio transmission, and broadcasting systems.
