Microchip Technology MICRF022BN

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 Micrel’s latest QwikRadio^tm
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.
