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 (VDD) applied while the negative supply voltage (VSS) 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.
