RF Switches (SPxT, DPxT)
Infineon offers a variety of RF Switches for mobile applications like 3G/4G phones and other battery operated systems. The portfolio starts from SPDT (Single-Pole/Dual-Throws) to highly complex DPxT (Dual-Pole/Multi-Throw) switches including cross-switching functionality controlled via GPIO (General Purpose Input/Output) or the standardized MIPI RFFE (Mobile Industry Processor Interface for RF Front-End) Interface. Besides the general RF applications, our RF switches also support multiband configurations in the receiving- and transmitting paths of 3G/4G cellular system, including CA (Carrier Aggregation).
Our RF Switches are produced in high volume with proven Bulk CMOS technology at several factories and packaged either in very small plastic package best for PCB (Printed Circuit Board) mounting or in CSP (Chip Scale Package) ideal for highly integrated modules.
- Up to 6GHz frequency range
- Very low insertion loss <0.2dB
- Small package size down to 0.65x0.98mm
- Standard Bulk CMOS Technology in high volume factories
