RadioWire® Transceivers
 Micrel's RadioWire™ products are a family of FSK (Frequency Shift Keying) highly integrated transceiver radio chips. The family targets Industrial, Scientific and Medical (ISM) license-free band applications. They also can be programmed to operate at different frequencies.
The RadioWire™ products have very low standby current and are perfect for battery operated applications like remote meter reading, remote keyless entry and wireless earphone. The family of products have low cost and high data rate. These make them a good alternative to Bluetooth and 802.11a/b/g solutions. RadioWire™ transceivers are ideal for long-range (1000m to 2 miles) and higher data-rate (128kbps) applications where bidirectional data exchange is required. For low data-rate, short-range applications, use our QwikRadio ® receivers and transmitters. |
