3P3T MIPI 2.1 antenna cross switch The BGSX33M5U16 RF CMOS switch is specifically designed for LTE and 5G antenna applications. This 3P3T 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. 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 2.0 mm and a thickness of 0.6 mm.
