Revision 3.1 - 2016-11-03 BGSX28MA18 BGSX28MA18 DP8T Diversity Cross Switch for Carrier Aggregation 1 Features * RF CMOS DP8T diversity switch with power handling capability of up to 27 dBm * Industry's first flexible carrier aggregation switch via cross switch functionality of one port * Device configurations SP4T/SP4T and SP5T/SP3T featured via cross switch functionality * Suitable for LTE carrier aggregation applications * Ultra-low insertion loss and harmonics generation * 0.1 to 3.8 GHz coverage * High port-to-port-isolation * No decoupling capacitors required if no DC applied on RF lines * Integrated MIPI RFFE interface operating in 1.1 to 1.95 V voltage range * Software programmable MIPI RFFE USID * Leadless and halogen free package ATSLP-18 with lateral size of 2.0 mm x 2.4 mm and thickness of 0.6 mm * No power supply blocking required * High EMI robustness * RoHS and WEEE compliant package 2 Product Description The BGSX28MA18 RF CMOS switch is specifically designed for LTE carrier aggregation applications. This DP8T offers low insertion loss and low harmonic generation. In addition, one port features cross functionality enabling higher flexibility for carrier aggregation applications. The switch is controlled via a MIPI RFFE controller. The on-chip controller allows power-supply voltages from 1.1 to 1.95 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 BGSX28MA18 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 2.0 x 2.4 mm2 and a maximum thickness of 0.6 mm.

When all triggers disabled, if writing to a register that is associated to trigger 2, the data goes directly to the destination register. If this bit is set, trigger 1 is disabled. When all triggers disabled, if writing to a register that is associated to trigger 1, the data goes directly to the destination register. If this bit is set, trigger 0 is disabled. When all triggers disabled, if writing to a register that is associated to trigger 0, the data goes directly to the destination register. A write of a one to this bit loads trigger 2's registers. A write of a one to this bit loads trigger 1's registers. A write of a one to this bit loads trigger 0's registers. These are read-only bits that are reserved and yield a value of 0b00 at readback.
