The ADRF5740 is a silicon, 4-bit digital attenuator with 22 dB attenuation control range in 2 dB steps.
The ADRF5740 operates from 10 MHz to 60 GHz with less than 3.3 dB of insertion loss and with ±(0.2 + 7.0% of attenuation state) of attenuation accuracy at 55 GHz. The ATTIN port of the ADRF5740 has an RF input power handling capability of 24 dBm average and 24 dBm peak for all states.
The ADRF5740 requires a dual supply voltage of +3.3 V and −3.3 V. The ADRF5740 features parallel mode control, and CMOS- and low voltage transistor to transistor logic (LVTTL)-compatible controls.
The ADRF5740 RF ports are designed to match a characteristic impedance of 50 Ω. The ADRF5740 comes in a 16-terminal, 2.5 mm × 2.5 mm, RoHS compliant, land grid array (LGA) package and operates from −40°C to +105°C.

Evaluation Kits (1)
The ADRF5740-EVALZ-185 and the ADRF5740-EVALZ-292 are designed to evaluate the features and performance of the ADRF5740 10 MHz to 60 GHz, 4-bit digital attenuator manufactured in a silicon process. The ADRF5740-EVALZ-292 is populated with 2.92 mm RF connectors, whereas the ADRF5740- EVALZ-185 (see Figure 1) is populated with 1.85 mm RF connectors.
For full details on the ADRF5740, see the ADRF5740 data sheet, which must be consulted in conjunction with this user guide when using the ADRF5740-EVALZ-185 or the ADRF5740-EVALZ-292.
Tools & Simulations
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
