MICRF003BMRF/IF射频/中频RFID的射频接收器规格书PDF中文资料

General Description

The MICRF003 is a single chip OOK (ON-OFF Keyed) Receiver IC for remote wireless applications, employing Micrel’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 MICRF003 is a true single-chip radio receiver, it is extremely easy to apply, minimizing design and production costs, and improving time to market.
