Description

The MICRF022BMFS24 is a single-chip OOK (ON-OFF Keyed) Receiver IC for remote wireless applications in the RF Receiver product category. It is an enhanced version of the MICRF001 and MICRF011, utilizing Micrel's QwikRadio tm technology. The device is designed as a true "antenna-in, data-out" monolithic device, featuring automatic RF and IF tuning without the need for manual adjustment, reducing production costs. With integrated receiver functions, it offers a reliable and cost-effective solution for high-volume wireless applications.
