ADRF5474 Image

The ADRF5474 from Analog Devices is a 4-Bit Silicon Digital Attenuator that operates from 10 MHz to 60 GHz. It provides an attenuation of 22 dB in 2 dB steps with an accuracy of ±0.4 dB. This attenuator can handle an input power of up to 24 dBm and has an insertion loss of less than 4 dB. It requires a dual DC supply of +3.3 and -3.3 V and features parallel mode control with CMOS/LVTTL compatible controls. The ADRF5474 is available in a 16-pad surface-mount package that measures 2.795 x 1.645 x 0.445 mm. It is ideal for use in industrial scanners, test and instrumentation, cellular infrastructure (5G millimeter-wave), military radios, radars, electronic countermeasures (ECMs), microwave radios, and very small aperture terminals (VSATs) applications.
