RFMicron’s Chameleon™ technology is a CMOS circuit embedded into a standards-compliant chip (the Magnus™ IC) for use in UHF RFID tags and wireless passive sensors.

The circuit gives the chip the unique ability to re-tune itself as conditions change around the tag. The circuit dynamically adjusts the chip’s input impedance to correct for impedance mismatches that occur when external influences alter the impedance of the tag’s antenna. Tags using the chip will perform more consistently and will remain functional in circumstances where other tags may fail.
