The HS8718-31 is a low loss SP8T switch with performance for antenna switch. The HS8718-31 is compatible with +1.35 V control logic, which is a key requirement for most cellular transceivers. This part is packaged in a compact 2 mm x 2 mm, 14-pin, QFN package which allows for a small solution size with no need for external DC blocking capacitors (when no external DC is applied to the device ports). A functional block diagram is shown in Figure 1.
• Excellent insertion loss and isolation performance
• Multi-Band operation 0.1 to 3.0 GHz
•Compact 2 mm x 2 mm in QFN-14 package
• No DC blocking capacitors required (unless external DC is applied to the RF ports)
• 2G/3G/4G antenna diversity
• Cellular modems and USB Devices
