Device Overview
Summary
The MICRF011 is a single chip OOK (ON-OFF Keyed) Receiver IC for remote wireless
applications, employing QwikRadio technology. This device is a true “antenna-in, data-out”
monolithic device. All RF and IF tuning is accomplished automatically within the IC, which
eliminates manual tuning and reduces production costs. Receiver functions are completely
integrated. The result is a highly reliable yet extremely low cost solution for high volume
wireless applications. Because the MICRF011 is a true single-chip radio receiver, it is
extremely easy to apply, minimizing design and production costs, and improving time to
market.
