Infineon Technologies BGSA143ML10 Low Resistance Antenna Tuning Switch
Infineon Technologies BGSA143ML10 Low Resistance Antenna Tuning Switch is a versatile Single-Pole Quad Throw (SP4T) RF Switch featuring open or short reflective ports optimized for tuning applications up to 6.0GHz. Including an RFFE Digital Control Interface, the BGSA143ML10 Switch offers the possibility to adopt an SP4T, SP3T, SPDT, or SPST topology for a wide range of flexibility in RF Front-End designs.
The BGSA143ML10 Switch includes 4 ultra-low RON series ports and 4 individually switchable shunt switches to enable open-reflective and short-reflective behavior. As a result any type of antenna tuning switching or tuner circuits can be realized with this device. The BGSA143ML10 integrates on-chip CMOS logic driven by a simple, single-pin CMOS or TTL compatible control input signal. Unlike GaAs technology, the 0.1dB 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. Due to its very high RF voltage ruggedness, the BGSA143ML10 is suited for switching any reactive devices such as inductors and capacitors in RF matching circuits without significant losses in quality factors.
The BGSA143ML10 Antenna Tuning Switch is offered in a compact 1.1mm x 1.5mm TSLP-10 package, ideal for space-constrained applications.
