Infineon Technologies BGSA144ML10 Ultra High RF Antenna Tuning Switch

Infineon Technologies BGSA144ML10 Ultra High RF Antenna Tuning Switch is a Single-Pole Four-Throw (SP4T) Switch optimized for RF applications up to 7.125GHz. The BGSA144ML10 integrates four low ON resistance/low OFF capacitance series switches and four shunt-to-ground switches enabling on-demand open-reflective or short-reflective OFF ports behavior. This feature reduces antenna engineer development time due to unwanted antenna resonance and improves antenna efficiency with less component tuning effort.

Infineon Technologies BGSA144ML10 Antenna Tuning Switch is available in a compact 1.1mm x 1.5mm PG-TSLP-10-3 package ideal for space-constrained applications.

Features

Low R_ON resistance of 1.74Ω at each RF port in ON state
Ultra-low C_OFF capacitance of 89fF in OFF state
Individually controlled reflective open or short to ground OFF ports to eliminate unwanted antenna resonances
High RF operating voltage handling 80V in OFF state

MIPI RFFE 2.1 compliant control interface
External USID_SEL pin enabling 4 default USID addresses
1.1mm x 1.5mm PG-TSLP-10-3 package
MSL1, 260°C per JEDEC J-STD-020

Applications

Impedance, antenna, and inductance tuning
