SKY13598-683LF Block Diagram Description The SKY13598-683LF is a state-of-the-art CMOS, silicon-oninsulator (SOI) double-pole, double-throw (DPDT) switch. The switch provides high-linearity performance, low insertion loss, and high isolation. Switching is controlled by one voltage input, CTRL1. Depending on the logic voltage level applied to this pin, the PORT1 and PORT2 pins connect to one of the two other RF port pins (PORT3 or PORT4) through a low insertion loss path, while maintaining a high isolation path to the alternate port. No external DC blocking capacitors are required on the RF path as long as no DC voltage is applied externally. The SKY13598-683LF DPDT switch is provided in a compact Quad Flat No-Lead (QFN) 1.83 × 1.83 × 0.5 mm package.
