CHR2244QDG/20 United Monolithic Semiconductors
RF Transceiver Module
MFG Part Number: CHR2244-QDG
    
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).
