The Infineon Low resistance antenna is a versatile shunt to ground 4 x single-pole single-throw (4xSPST) RF antenna tuning switch, it is optimized for low Coff as well as low Ron enabling applications up to 7.125 GHz and is ideal for antenna tuning application also this chip integrates on-chip CMOS logic and power supply regulation., its digital control interface is compliant with MIPI2, RFFE specification and each switch throw can be programmed individually or all together in the same RFFE command frame.

Low Ron resistance of 2 ohm at each point in ON state
Low Coff capacitance of 165 fF at each port in OFF state
High RF operating peak voltage handling of 90 V in OFF state
MIPI RFFE 2.1 control interface
Extremely low current consumption of 22 μA
4 default USID addresses via external USID_SEL pin
