AK2364

RF Detectors Overview

The AK2364 is a two-way radio filterless FM detector LSI manufactured by Asahi Kasei Microdevices. Designed for direct frequency modulation detection, this integrated circuit eliminates the need for external filtering components in receiver architectures. The device operates at a center frequency of 57.6 MHz and is housed in a compact 28-pin QFN package. It provides a dedicated output signal representing the demodulated audio information from FM broadcast signals.
