ADRF5144 10 W Average, Silicon SPDT, Reflective Switch, 1 GHz to 20 GHz

Product Details

The ADRF5144 is a reflective, single pole double-throw (SPDT) switch manufactured in the silicon process.

The ADRF5144 operates from 1 GHz to 20 GHz with typical insertion loss of 0.8 dB and typical isolation of 52 dB. The device has a radio frequency (RF) input power handling capability of 40 dBm average power and 44 dBm peak power for the insertion loss path.

The ADRF5144 draws a low current of 130 μA on the positive supply of +3.3 V and 510 μA on negative supply of −3.3 V. The device employs complementary metal-oxide semiconductor (CMOS)-/low-voltage transistor to transistor logic (LVTTL)-compatible controls. The ADRF5144 requires no additional driver circuitry, which makes it an ideal alternative to GaN and PIN diode-based switches.

The ADRF5144 can also operate with a single positive supply voltage (V_DD) applied while the negative supply voltage (V_SS) is tied to ground. In this operating condition, the small signal performance is maintained while the switching characteristics, linearity, and power handling performance are derated, see Table 2 in the data sheet.

The ADRF5144 comes in a 20-lead, 3.0 mm × 3.0 mm, RoHS-compliant, land grid array (LGA) package and can operate from −40°C to +85°C.
