RF digitally tunable capacitor + SPDT switch
BGSC2341ML10 is a versatile Integrated Circuit (IC) ideal for RF tuning applications such as tunable impedance matching, antenna tuning and tunable filtering. This IC integrates an 8-states tunable capacitor and an extremely low RON Single Pole Double Throw (SPDT) RF switch function; both controlled by on-chip MIPI 2.1 RFFE digital interface.
Unlike some other tunable capacitor technologies, Infineon Bulk CMOS ensures very stable capacitance step values over the entire -40...+85° C temperature range. Last but not the least, BGSC2341ML10 exhibits very good linearity in high RF power conditions and up to RF voltage greater than 39 V which is a key attribute in application like antenna tuning. It does not require any additional High Voltage Supply Controller IC and can be powered by a single 1.8 V power supply at an extremely low current consumption level. With 1.1 mm x 1.5 mm package dimensions, it is a compact solution fitting well to any small form factor mobile phone-like applications.
