Infineon Technologies Antenna Cross Switches

Infineon Technologies Antenna Cross Switches are engineered for advanced 5G SRS applications, delivering exceptional performance with high linearity of up to 39dBm input power. The switches enable switching between antennas to select the best-performing antenna for optimizing transmit power for an Up-Link (UL) or improved receive sensitivity for a Down-Link (DL). The antenna cross switches boast low current consumption, making the components efficient for energy-sensitive designs while maintaining low insertion loss for optimal signal integrity. With high port-to-port isolation of up to 7.125GHz, the devices effectively minimize interference between channels. The Infineon Technologies antenna cross switches also feature a maximum rapid switching time of just 2µs, ensuring quick response and reliable operation in dynamic communication environments.
