The ADRF5031 from Analog Devices is a Silicon SPDT Non-reflective switch that operates from 9 kHz to 20 GHz. It has a switching speed of 3 us, provides an isolation of 45 dB and an insertion loss of less than 1 dB. This silicon switch can handle an input power of 33 dBm (~2 W), a peak input power of 35 dBm (~3.16 W), and has a return loss of 17 to 22 dB. It employs complementary metal-oxide semiconductor (CMOS)-/low-voltage transistor to transistor logic (LVTTL)-compatible controls and does not require additional driver circuitry, making it an ideal alternative to GaN and PIN diode-based switches.
The ADRF5031 requires DC supplies of +3.3 and -3.3 V and consumes 150 µA (positive supply) and 520 µA (negative supply) of current. This RoHS-compliant switch is available in a 20-terminal LGA package that measures 3 × 3 mm. It is ideal for test instrumentation, military radios, radars, electronic counter measures (ECMs), microwave radios, and very small aperture terminals (VSATs) applications.
