ADI’s ADRF5021 are general-purpose single-pole, double-throw (SPDT) switches manufactured using a silicon process. The devices comes in an ultra-small 3 mm × 3 mm, 20-lead land grid array (LGA) package and provide high isolation and low insertion loss from 9 kHz to 30 GHz. The ADRF5021 requires dual supply voltages, +3.3 V and -2.5 V, and provides complementary metal-oxide semiconductor (CMOS) / low voltage transistor transistor logic (LVTTL) logic-compatible control. These devices were designed with microwave, radio, and telecom applications in mind.
