Ultra-small 2xSPST antenna tuning switch The BGSA200ML9 is a versatile shunt to ground 2 x Single-Pole Single-Throw (2xSPST) RF antenna tuning switch. It is optimized for low COFF as well as low RON enabling applications up to 8.25GHz; ideally fitting for antenna tuning purpose. The BGSA200ML9 integrates on-chip CMOS logic and power supply regulation. Thanks to its 4 states USID1 and USID2 feature, it can be controlled either with GPIO lines or MIPI RFFE bus. Each switch throw can be programmed individually or altogether. Up to 3 instantiations of the same device can be controlled using the same RFFE bus when in MIPI RFFE mode.
