Product Details

The ADRF5740 is a silicon, 4-bit digital attenuator with 22 dB attenuation control range in 2 dB steps.

This device operates from 500 MHz to 60 GHz with better than 3.2 dB (TBC) of insertion loss and excellent attenuation accuracy. The ATTIN port of the ADRF5740 has a radio frequency (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 device features parallel mode control, and complementary metal-oxide semiconductor (CMOS)-/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.

Applications

  • Industrial scanners
  • Test and instrumentation
  • Cellular infrastructure: 5G millimeter wave
  • Military radios, radars, electronic counter measures (ECMs)
  • Microwave radios and very small aperture terminals (VSATs)
