Introdução
WF531RA is a highly integrated, low-power single-chip ASK/OOK RF receiver chip. The high-frequency signal receiving function is fully integrated in the chip to achieve the most reliable reception effect with the least peripheral devices and the lowest cost. Therefore, it is a single-chip receiving device with “entrada de sinal de modulação de alta frequência sem fio e saída de sinal de demodulação digital” no verdadeiro sentido.
WF531RA is a SOP8 package with a normal operating voltage range of 2.0-5.5V, a normal operating current of 5mA, a start-up time of 3ms, and a maximum receiving sensitivity of -113dBm, which is very suitable for various low-power devices. All RF and IF tuning are automatically completed in the chip, and the manual adjustment process is omitted in development and production, thereby reducing costs and accelerating product launch.
