  • Product Description
    • Commodity name: BK4815N Half duplex time-division multiplexing FM transceiver, suitable for global walkie talkie applications.

    Overview
    BK4815N is a half duplex time-division multiplexing FM transceiver, operating in the frequency range of 115MHz~537MHz, suitable for global walkie talkie applications. In addition to voice communication, it also supports FSK modulation/demodulation in both F2D and F1W formats, which can be used for sending and receiving GPS coordinates and other short messages. Equipped with four IQ analog outputs, suitable for DPMR and DMR digital intercom applications.
    The characteristics of BK4815N are low power consumption, high performance, high integration, small package size, suitable for handheld consumer and industrial applications. Only one 26M crystal, one inductor for RF matching, and several decoupling capacitors are needed on the PCB to complete a fully functional walkie talkie application.
