CHR2270-QRG
5.8GHz Transponder
SiGe Monolithic Microwave IC in SMD leadless package
Description
The CHR2270-QRG is an integrated transponder circuit, manufactured in SiGe technology and designed to be compatible with ETSI ES 200 674 and EN 300 674 dedicated to short-range communications at 5.8GHz. It includes all the RF functions for bidirectional transmission and digital interfaces to controller, with high flexibility for performances customization. Three modes are implemented: STANDBY: ultra-low current AM detector, with integrated RF filtering, providing a selective wake-up signal on SB_out & SB_CPT outputs. These outputs are active when an AM modulated RF signal is applied to the RF input with either ETSI ES 200 674 or EN 300 674 patterns.
