Infineon Technologies BGSX44MA12 4P4T RX switch

The BGSX44MA12 RF CMOS switch is specifically designed for LTE and WCDMA Receive path applications. This 4P4T offers low insertion loss and low harmonic generation.

The switch is controlled via a MIPI RFFE controller. The on-chip controller allows power-supply voltages from 1.65 to 1.95 V.

The BGSX44MA12 RF Switch is manufactured in Infineon’s patented MOS technology, offering the performance of GaAs with the economy and integration of conventional CMOS including the inherent higher ESD robustness. The device has a very small size of only 1.6 x 1.6 mm2 and a maximum thickness of 0.6 mm.
