The ADRF5022 from Analog Devices is a Silicon SPDT Switch that operates from 100 MHz to 45 GHz. It has an ON/OFF switching time of 20 ns, provides an isolation of up to 60 dB and has an insertion loss of less than 2.3 dB. This non-reflective switch can handle an RF input-power of 30 dBm for the through path, 24 dBm for the terminated path, and 30 dBm for the hot switching at the RF common port. It requires a dual DC supply of +3.3 V and -3.3 V and consumes less than 510 μA of current. The switch employs complementary metal-oxide semiconductor (CMOS)-/low-voltage transistor to transistor logic (LVTTL)-compatible controls.
The ADRF5022 can also operate with a single positive supply voltage applied while the negative supply voltage (VSS) is connected to the ground. In this operating condition, the small signal performance is maintained while the switching characteristics, linearity, and power handling performance are derated. It is available in a 20-terminal LGA package that measures 3 x 3 mm and is ideal for use in test and instrumentation, cellular infrastructure (5G millimeter wave), military radios, radars, and electronic countermeasures (ECMs), microwave radios, very small aperture terminals (VSATs) and industrial scanner applications.
