Part details & applications

The ADRF5476 is a silicon, 2-bit digital attenuator with 12 dB attenuation control range in 4 dB steps.

The ADRF5476 is specified from 1 GHz to 72 GHz with less than 3.0 dB of insertion loss and with ±0.75 dB step error at 72 GHz. The device can operate bidirectionally, the ATTIN and ATTOUT ports of the ADRF5476 have an RF power handling capability of 24 dBm average and 24 dBm peak for all states.

The ADRF5476 draws a low current of 120 μA on the positive supply of +3.3 V and 520 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 ADRF5476 RF ports are designed to match a characteristic impedance of 50 Ω.

The ADRF5476 is a 14-ball, 1.940 mm × 1.160 mm, bumped bare die sales and can operate between −40°C to +105°C.
