RR285 is a highly integrated, low power ASK/OOK RF receiver chip in SOP8 package. The high matching signal part is integrated into the chip to obtain reliable reception with the least peripheral devices and the lowest cost; the RF and IF tuning is done automatically on the chip, which omits the manual adjustment during the development and production process, and thus reduces the cost.
