The ADRF5440 is a reflective, SP4T switch manufactured in the silicon process. This switch operates from 1GHz to 81GHz with better than 4.0dB of insertion loss and 20dB of isolation. The ADRF5440 has an RF input power handling capability of 24dBm for the through path and 24dBm for hot switching.

The ADRF5440 draws a low current of 145μA on the positive supply of +3.3V and 510μA on negative supply of −3.3V. The device employs complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatible controls.

The ADRF5440 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 is derated. See Table 2 in the data sheet for more details.

The ADRF5440 RF ports are designed to match a characteristic impedance of 50Ω. The ADRF5440 is 56-ball, 2.390 mm x 2.540 mm, bumped bare die sales and can operate between −40°C to +105°C.
