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 0.85 dB and typical isolation of 48 dB. The device has a radio frequency (RF) input power handling capability of 40 dBm average power and TBD dBm peak power for the insertion loss path. The ADRF5144 also supports extended frequency range of 9 kHz to 26.5 GHz with derated power handling capability below 1 GHz and above 20 GHz.

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, making it an ideal alternative to GaN and PIN diode-based switches.

The ADRF5144 can also operate with a single positive supply voltage (VDD) applied while the negative supply voltage (VSS) is tied to ground. In this operating condition, the small signal performance will be maintained while the switching characteristics, linearity and power handling performance will be 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.
