BGSA147ML10 ultra-low resistance SP4T antenna tuner
BGSA147ML10 is a Single-Pole Four Throws (SP4T) Antenna Tuning switch optimized for RF applications up to 7.125 GHz. Its MIPI RFFE digital control interface allows easy implementation and best flexibility when operated in cellular mobile RF Front-End designs.
BGSA147ML10 is made of 4 ultra-low ON resistance / low OFF capacitance series switches and 4 shunt to ground switches enabling on-demand open-reflective or short-reflective OFF ports behaviour. 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.
Unlike GaAs RF switches, highly linear RF performance is reached at all signal levels within the operating conditions. High RF voltage ruggedness and individually programmable shunt to ground switches on each RF throw make BGSA147ML10 particularly efficient for switching inductors and capacitors in RF matching and antenna tuning circuits.
Summary of Features
Designed for high-linearity antenna tuning switching and RF tuning applications
Ultra low RON resistance of 0.8 Ω at each RF port in ON state
Individually controlled reflective open or short to ground OFF ports to eliminate unwanted antenna resonances
Low COFF capacitance of 155 fF at each port in OFF state
High RF operating voltage handling above 45 V in OFF state
MIPI RFFE 2.1 compliant control interface
External USID_sel pin enabling 3 default USID addresses
No RF parameter change within supply voltage range
No blocking capacitors required if no DC applied on the RF lines
No power supply decoupling required
Small form factor 1.1 mm x 1.5 mm x 0.39 mm (MSL1, 260° C per JEDEC J-STD-020)
RoHS and WEEE compliant package
Potential Applications
Impedance tuning
Antenna tuning
Inductance tuning
Tunable filters
