Features & Applications
The MICRF007YM TR is a single chip ASK/OOK (ON-OFF Keyed) Receiver IC for remote wireless applications, employing Micrel’s latest QwikRadio® technology. It comes in SOIC-8 Package.

This device is a true “antenna-in to data-out” monolithic device. All RF and IF tuning is accomplished automatically within the IC which eliminates manual tuning, and reduces production costs. The result is a highly reliable yet extremely low cost solution. The MICRF007 is an enhanced version of the MICRF002 and MICRF011.
