UMS announce digital short range communication transponder
UMS has announced the release of an innovative Digital Short Range Communication transponder. This 3rd generation product combines the advantages of key technologies such as SiGe and QFN plastic package in order to provide a multi-normative fully compliant device. In operation, this transponder offers as long as 5 years lifetime without maintenance.
The CHR2270-QRG operates at 5.8GHz and is designed for a wide range of applications:
· Short and medium range automotive communication (DSRC),
· Electronic Traffic Control (ETC)
· Identification transponders.
This product features a very low power consumption which can result in 5 years battery life.
The CHR2270-QRG provides the following features:
< Single RF antenna port to allow compact systems
< Integrated high selectivity wake-up
< Ultra low Standby current
< 3V battery bias voltage range
< Downlink RF input power monitoring
< Uplink gain control
< -25°C to +90°C operating temperature range
< More than 5 years battery life,
< Plastic package (QFN-24),
< ESD protection.
Three operating modes are implemented:
< STANDBY: ultra low current AM detector, providing a wake-up signal (high selectivity system avoiding untimely wake-up) on SB-Out output.
< DOWNLINK: low current AM detector, with optimized IF bandwidth.
< UPLINK: multiplier based on a passive reflective mixer.
The circuit is designed to be fully compliant with the ETSI EN 300674, ETSI 200674 and Italian norms.
