BGSX44MU18

Active and preferred

The BGSX44MU18 RF CMOS switch is specifically designed for LTE and 5G FR1 four-antenna applications. This 4P4T cross-switch offers low insertion loss and low harmonic generation.The switch is controlled via a MIPI RFFE control interface. The on-chip controller allows power-supply voltages from 1.65 to1.95 V. The switch features direct-connect-to-battery functionality and DC-free RF ports.Unlike GaAs technology, external DC blocking capacitors at the RF ports are only required if DC voltage is applied externally. The device has a very small size of only 2.0 mm x 2.4 mm and a thickness of 0.63 mm.
