Wireless IC

U1R32D Is a receiving chip used for wireless audio transmission, combined with the wireless transmission chip to complete high-quality wireless audio transmission. The RF operating range is between 500 M and 980 MHz of the UHF. Due to the integration of DSP core and necessary peripherals, the single chip has high integration degree and good cost performance. Suitable for wireless K song system, wireless audio transmission and broadcasting system.
