SKYA21037 block diagram description the SKYA21037 is a state-of-the-art cmos, silicon-on- insulator (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 SKYA21037 dpdt switch is provided in a compact quad flat no-lead (qfn) 2 x 2 mm package. a functional block diagram is shown in figure 1.
