PRELIMINARYQPC1252QBROADBAND HIGH LINEARITY DSDA e-CALL ANTENNA ROUTING SWITCHNCEDProduct Overview The QPC1252Q is a low loss, high linearity antenna routing switch that is designed to enable Emergency Calling (e-Call) functionality in the telematics control unit (TCU) supporting Dual Sim Dual Active (DSDA). In the case of an emergency situation where antennas may become damaged or covered, the QPC1252Q allows a primary cellular link to be switched to other antennas in the automobile to establish emergency communication. A power splitter is incorporated for single antenna distribution for DSDA applications. The control interface for the QPC1252Q is an RFFE serial control system that is compliant with the V2.1 MIPI standard. 32 Pin 4.0 x 6.0 X 0.64 mm3 Module Functional Block DiagramKey Features • Qualified to AEC-Q100 Grade 2 (target) • Integrated 3GHz splitter with bypass for DSDA applications • Excellent insertion loss and Isolation performance QPC1252Q • High linearity • RFFE V2.1 control interface ANT1RF1 • Broadband performance suitable for multiple air Interfaces including 5G applications up to 6 GHz • Very low current consumption • DC blocking capacitors not required in typical application ANT2RF2 • Single Vio supply • Hot Switching Input power up to +34 dBm ANT3RF3ApplicationsANT4RF4 • eCall switching applications • Telematic Control Unit Modules RF5Part NumberDescription QPC1252QSB 5 PC Sample Bag RFFE RF6 CONTROLLER QPC1252QDK Design Kit 13" tape and reel, non-standard QPC1252QTR13X quantity only Switches shown in normal operation mode Dashed lines indicate e-Call modes QPC1252Q Preliminary DS RevA | Subject to change without notice 1 of 17 www.qorvo.com
