CHR2244-QDG
RoHS COMPLIANT
5.8 GHz One Antenna Reflective Transponder for Tag
GaAs Monolithic Microwave IC
Description
The CHR2244 is a MMIC transponder dedicated to
short range communications at 5.8GHz. It includes
all the RF functions for bi-directional transmission
and CMOS compatible interfaces. Only one
antenna is necessary.
Three modes are implemented:
STANDBY: ultra low current AM detector, with a
reduced bandwidth, providing a wake-up signal on
SB_out output. This signal is a DC voltage. This
output is active when and only when an AM
modulated RF signal is applied to the RF input.
DOWNLINK: low current AM detector, with
optimized IF bandwidth, providing the demodulated
data at the CMOS compatible DATA_out output.
UPLINK: multiplier based on a passive reflective
mixer.
This circuit is manufactured on a MESFET
process. It is supplied in plastic package (QFN-24).
