The ADRF5476 is a silicon, 2-bit digital attenuator with a 12dB attenuation range with a 4dB step size. The ADRF5476 is specified from 1GHz to 72GHz with less than 3.0dB of insertion loss and with ±0.75dB step error at 72GHz. The device can operate bidirectionally, the ATTIN and ATTOUT ports of the ADRF5476 have an RF power handling capability of 24dBm average and 24dBm peak for all states. The ADRF5476 draws a current of +124μA on the positive supply of +3.3V and −528μA on negative supply of −3.3V. 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 50Ω. The ADRF5476 is a 14-ball, 1.940mm × 1.160mm, bumped bare die sales and can operate between −40°C to +105°C.
