描述 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 Figure 1 (see Datasheet). The module comes in a miniature LGA Package and comprises of a 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.
