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 bi-directional transmission and digital interfaces to controller, with very high flexibility for performance customization and very low current consumption in iddle mode.
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.
DOWNLINK: low current AM detector, with optimized IF bandwidth, providing the demodulated data at the Data_out output.
UPLINK: multipliers based on passive reflective mixers operating either in phase or amplitude modulation.
