MICRF022BM

RF Receiver ASK/OOK 5V 8Pin SOIC N

General Description

The MICRF002, an enhanced version of the MICRF001 and MICRF011, is a single chip OOK ON-OFF Keyed Receiver IC for remote wireless applications, employing ’s latest QwikRadiotm

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 MICRF002 is a true single-chip radio receiver , it is extremely easy to apply , minimizing design and production costs, and improving time to market.
