BGSA400ML10

Active and preferred

The BGSA400ML10 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 7.125GHz. The BGSA400ML10 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 4 instantiations of the same device can be controlled using the same RFFE bus thanks to its 4 states USID_SEL pin unique feature.
