BGSA147ML10

Active and preferred

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.
