The BGSF110GN26 is a Single Pole Ten Throw (SP10T) Antenna Switch Module (ASM) optimized for wireless applications up to 3.8 GHz. It is a perfect solution for multi-mode handsets based on quadband GSM, WCDMA and LTE. The switch module configuration is shown in Figure 1 (see datasheet). The module comes in a miniature TSNP package and comprises of a high power CMOS SP10T switch with integrated GPIO 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 3.1 V. No external DC blocking capacitors are required in typical applications as long as no DC is applied to any RF port.

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.
