The ADRF5424 from Analog Devices is a Reflective SPDT Switch that operates from 100 MHz to 60 GHz. It can handle an average input power of 27 dBm for both the through path and hot switching. The switch has a settling time of 17 ns, an insertion loss of less than 1.9 dB, and provides isolation of more than 30 dB. It uses complementary metal-oxide-semiconductor (CMOS)/low voltage transistor to transistor logic (LVTTL) compatible controls. The switch requires a DC supply of ±3.3 V and consumes less than 120 µA of current.
The ADRF5424 is manufactured using a silicon process and is attached to a gallium arsenide (GaAs) carrier substrate. The substrate incorporates the bond pads for chip and wire assembly, and the bottom of the device is metalized, connected to the ground. It is available in a 14-pad die on carrier chip that measures 2.471 x 2.571 mm and is ideal for use in test and instrumentation, cellular infrastructure: 5G millimeter wave, military radios, radars, electronic countermeasures (ECMs), microwave radios, and very small aperture terminals (VSATs).
