Infineon – Antenna Tuning switch -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.

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 COFFcapacitance 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

Benefits
– Support sub-7 GHz NR (5G)
