The BGSA402ML10 is a versatile shunt to ground 4xSingle-Pole Single-Throw (4xSPST) RF antenna tuning switch. It is optimized for low COFF as well as low RON enabling applications up to 6 GHz. The BGSA402ML10 is ideal for antenna tuning application. This chip integrates on-chip CMOS logic and power supply regulation. Its digital control interface is compliant with MIPI2.1 RFFE specification and each switch throw can be programmed individually or all together in the same RFFE command frame. Up to 2 instantiations of the same device can be controlled using the same RFFE bus thanks to its 2 states USIDSel pin. Unlike GaAs technology, the 0.1 dB compression point exceeds the switch maximum input power level, resulting in excellent linear performance at all signal levels within the operating conditions. External DC blocking capacitors at the RF ports are only required if DC voltage is applied externally. Due to its high RF voltage ruggedness, it is suited for switching any reactive device such as inductor and capacitor in RF matching circuits without significant losses.
