Ultra high RF voltage antenna tuning switch
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.
Summary of Features
Low RON resistance of 2.0 Ω at each port in ON state
Low COFF capacitance of 165 fF at each port in OFF state
High RF operating peak voltage handling of typical 90 V in OFF state
Low harmonic generation
MIPI RFFE 2.1 control interface
Extremely low current consumption of 22 µA
4 default USID addresses via external USID_SEL pin
Small form factor 1.1 mm x 1.5 mm (MSL1, 260 °C per JEDEC J-STD-020)
Potential Applications
Impedance, Antenna and Inductance Tuning
Tunable Filters
