BGSA143GL10

Active and preferred

BGSA143GL10 is a small and versatile Single-Pole Quad Throw (SP4T) RF switch optimized for low COFF as well as low RON enabling applications up to 6.0GHz. GPIO digital control lines offer the possibility to adopt SP4T, SPDT along with SPST topology for an optimum flexibility in RF Front-end designs. BGSA143GL10 is ideal for high Q tuning applications. This single supply chip integrates on-chip CMOS logic control. It can be driven by 2 or 3 CMOS or TTL compatible control input signals. Due to its high RF voltage ruggedness and OFF RF ports reflective short feature, it is suited for switching any reactive devices such as inductors and capacitors in RF matching circuits without significant losses, also mitigating or even eradicating unwanted parasitic RF resonances.
