The BGS18MA12 from Infineon is an SP8T Switch that operates from 0.1 to 6 GHz. It can handle an input power of 3 W, has an insertion loss of less than 1.8 dB, and provides more than 12 dB of isolation. This switch is based on Infineon’s proprietary technology and has an on-chip MIPI RFFE 2.0 controller that is fully compatible with industrial standards. It has a switching time of 3 μs, an RF rise time of less than 2 μs, and a power-up settling time of 10 μs. The switch requires a DC supply of 1.8 V, consumes less than 125 μA of current during normal operation, and 2 μA of current in idle mode. It does not require any decoupling capacitors if no DC voltage is applied on RF lines. This switch is available in a package that measures 1.1 x 1.9 x 0.6 mm and is suitable for use in LTE (Band 42/43), 5G, and LAA applications.
