The ADRF5162 from Analog Devices is a Silicon SPDT Reflective Switch that operates from 0.4 GHz to 8 GHz. It has a switching speed of 800 ns, provides an isolation of 45 dB and an insertion loss of less than 0.8 dB. This reflective switch can handle an input of power of 45.5 dBm (~38.5 W), a peak input power of 50 dBm (100 W) and has a return loss of 20 to 25 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 ADRF5162 requires DC supplies of +3.3 and -3.3 V and consumes 130 µA (positive supply) and 500 µA (negative supply) of current. This RoHS-compliant switch is available in a 24-lead LFCSP package that measures 4.0 x 4.0 x 0.85 mm. It is ideal for military radios, radars, electronic countermeasures, cellular infrastructure, test & instrumentation, and GaN & PIN diode replacement applications.
