Description

The BGSF18DM20 is a Single Pole Eight Throw (SP8T) switch module optimized for wireless applications up to

2.7 GHz. It is a perfect solution for multimode handsets based on GSM Quadband and WCDMA. The switch

module configuration is shown in

high power CMOS SP8T switch with integrated SPI controller and harmonic filters for GSM high and low band

transmit paths. The on-chip controller integrates CMOS logic and level shifters, driven by control inputs from 1.35

to 3.3 V. The module features direct-connect-to-battery functionality and DC-free RF ports.

The antenna port has integrated ESD protection to achieve 8kV ESD robustness without external components.
