描述 Description

The SKYA21037 is a state-of-the-art CMOS, silicon-oninsulator(SOI) double-pole, double-throw (DPDT) switch. Theswitch provides high-linearity performance, low insertion loss,and high isolation.

Switching is controlled by one voltage input (CTRL1). Dependingon the logic voltage level applied to this pin, the PORT1 andPORT2 pins connect to one of the two other RF port pins (PORT3or PORT4) through a low insertion loss path, while maintaining ahigh-isolation path to the alternate port. No external DC blockingcapacitors are required on the RF path as long as no DC voltage isapplied externally.

The SKYA21037 DPDT switch is provided in a compact Quad FlatNo-Lead (QFN) 2 x 2 mm package.
