ADRF5740BCCZN-R7

Attenuators Overview

The ADRF5740BCCZN-R7 is a silicon digital attenuator manufactured by Analog Devices Inc., designed for high-frequency applications up to 60 GHz. It features a 4-bit control interface with a least significant bit (LSB) step size of 2 dB, providing a total attenuation range of 22 dB. The device operates within a single channel configuration and maintains a standard 50 Ohm impedance. Key electrical specifications include an insertion loss of 4.4 dB and a frequency range spanning from 10 MHz to 60 GHz. It functions on a supply voltage between 3.15 V and 3.45 V, with an operating temperature range from -40°C to +105°C. The component is housed in an LGA-16 package.
