General Description

The MICRF008 QwikRadio™ UHF receiver is a single-chip OOK (on-off keyed) receiver IC designed for remote wireless applications. This device is a true single-chip, “antenna-in, data-out” device, and it is easy to implement. MICRF008 receiver requires very few peripheral passive components. All tunings, RF and IF, are accomplished within the IC. Ease of use and minimal parts count translate to cost savings and shorter time to market. MICRF008 receiver offers a robust and low-cost solution for high volume wireless applications.
