Features
 Low RON resistance of 1.74 Ω at each RF port in ON state
 Ultra low COFF capacitance of 89 fF in OFF state
 Individually controlled reflective open or short to ground OFF ports
to eliminate uwanted antenna resonances
 High RF operating voltage handling 80 V in OFF state
 MIPI RFFE 2.1 compliant control interface
 External USID_SEL pin enabling 4 default USID addresses
 Small form factor 1.1 mm x 1.5 mm (MSL1, 260 °C per JEDEC J-STD-020)

Description
The BGSA144ML10 is a single-pole four throws (SP4T) Antenna Tuning switch optimized for RF applications up
to 7.125 GHz.
The BGSA144ML10 is made of 4 low ON resistance / low OFF capacitance series switches and 4 shunt to ground
switches enabling on-demand open-reflective or short-reflective OFF ports behavior. This last feature is of great
value to reduce antenna engineer development time in case of unwanted antenna resonance or to improve
antenna efficiency with less component tuning effort.
