Infineon – BGSA142 family – high RF Voltage Antenna Tuning SP4T Switches

Infineon – BGSA142 family – high RF Voltage Antenna Tuning SP4T Switches

The BGSA142xxx is a versatile direct mapping Single-Pole Quad Throw (SP4T) RF switch optimized for low COFF as well as low RON enabling applications up to 6.0 GHz. The device includes 4 low RON and high RF voltage ports making it ideal for antenna tuning and tunable matching network applications. RFC as well as RF1, RF2, RF3 and RF4 can handle high RF voltage (bidirectional RF Voltage handling). Due to its very high RF voltage ruggedness on all RF ports, it is suited for switching any reactive devices such as inductors and capacitors without significant losses.Unlike GaAs technology, the 0.1 dB compression point exceeds the switch maximum input power level, resulting in linear performance at all signal levels and external DC blocking capacitors at the RF ports are only required if DC voltage is applied externally.

Features
– Designed for high linearity and high RF voltage tuning applica-tions
– Multiple selectable switch configurations:
– each throw directly and independently controlled
– Low RON resistance of 1.75 Ω at each port in ON state
– Low COFF capacitance of 110 fF at each port in OFF state
– High RF operating voltage of 72 V at RFx and 67 V at RFC in OFF state
– Low harmonic generation
– MIPI 2.0 RFFE control interface (for MIPI version)
– 3 GPIO pins control interface (for GPIO version)
– 1.8V supply voltage support (1.65V min)
– No RF parameter change within supply voltage range
– Small form factor 1.5 mm x 1.5 mm (MSL1, 260° C per JEDEC J-STD-020)
– RoHS and WEEE compliant package

Benefits
– Performance stability over full temperature and power supply range
– Good small and large signal RF performance up to 6GHz

Competitive advantage
– Fulfils latest Qualcomm chipset (SD865) 1.8V nominal supply volt-age rail requirement
– 4 USID addresses enabled by external condition at USID_sel pin and SCLK/SDATA swap mode (for MIPI devices)

Target applications
– high-linearity and high RF voltage antenna tuning applications
