Infineon - BGSC2341ML10 -RF digitally tunable capacitor + SPDT switch

Infineon – BGSC2341ML10 -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 RONSingle Pole Double Throw (SPDT) RF switch function; both controlled by on-chip MIPI 2.1 RFFE digital interface.

Features
– Designed for high-linearity applications
– Ultra low RONresistance of 0.87 Ωat each SPDT throw in ON state
– High operating RF Voltage handling 39 V
– 0.26-2.00 pF tuning range at 1.8 GHz
– Operating frequencies: 0.4 -3.8 GHz
– High ESD robustness
– MIPI 2.1 RFFE compliant control interface
– 2 default USID selectable via USID_SEL pin
– Supply voltage range: 1.65 to 1.95 V
– Small form factor 1.1 mm x 1.5 mm (MSL1, 260° C per JEDEC J-STD-020)
– RoHS and WEEE compliant package

Benefits
– Ultra low RON SPDT RF switch à Low RF losses in low Z system
– Extremely low Cmin and 8:1 capacitance tuning range (8 steps)
– Highly versatile usage

Competitive advantage
– 8 bits C-tuner for high resolution antenna fine-tuning
– PCB space saving via SPDT + RF C-tuner SoC integration into a very small 1.1×1.5mm package

Target applications
– All battery powered cellular applications
