CHR2270-QRG Datasheet Transponder

Manufacturer: United Monolithic Semiconductors

Overview: CHR2270-QRG 5.8GHz Transponder SiGe Monolithic Microwave IC in SMD leadless.

General Description

The CHR2270-QRG is an integrated transponder circuit, manufactured in SiGe technology and designed to be patible with ETSI ES 200 674 and EN 300 674 dedicated to short-range munications 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.
