AK2365A

RF Detectors Overview

The AK2365A is an RF detector IC designed for FM intermediate frequency applications, operating within a frequency range of 45.9 MHz to 57.6 MHz. It integrates a second mixer, automatic gain control with bandpass filter, PLL FM detector, noise squelch, and RSSI circuitry. The device supports a supply voltage from 2.6 V to 5.5 V and functions at temperatures between -40 °C and +85 °C. Packaged in a 32-pin QFNJ-32 surface-mount format, it replaces external E to J type ceramic filters.
