Infineon – BGSA143GL10 – RF switch optimized for low COFF as well as low RON

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.
