General Description
The MICRF007 is a single chip, ON-OFF Keyed (ASK/OOK) Receiver for remote wireless applications, employing Micrel’s latest QwikRadio®technology. 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.
