The SKY13598-683LF from Skyworks is a CMOS, silicon-on-insulator (SOI) DPDT switch that operates from 0.4 to 3.8 GHz. It provides high-linearity performance with an insertion loss of 0.7 dB and has an isolation of 38 dB. The switch can handle a power of up to 8 Watts and requires a supply voltage of 1.35 to 3.1 volts. It is available in a compact QFN package that measures 1.83 x 1.83 x 0.5 mm and is ideal for LTE systems & main/diversity antenna swapping applications. No external DC blocking capacitors are required on the RF path as long as no DC voltage is applied externally.
