Description
BGSA143ML10 is a versatile Single-Pole Quad Throw (SP4T) RF antenna tuning switch featuring open or short
reflective ports, being optimized for tuning applications up to 6.0 GHz. Including a RFFE digital control
interface, this switch offers the possibility to adopt a SP4T, SP3T, SPDT along with SPST topology for a better
flexibility in RF Front-End designs.
BGSA143ML10 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. This single supply chip integrates on-chip CMOS logic driven by a simple, single-pin CMOS or TTL
compatible control input signal. 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. Due to its very high RF voltage
ruggedness, it is suited for switching any reactive devices such as inductors and capacitors in RF matching
circuits without significant losses in quality factors.
