The ADRF5700 is a silicon, 5-bit digital attenuator with 46 dB attenuation control range in 2 dB steps.

This device operates from 100 MHz to 22 GHz with better than 2.0 dB of insertion loss and high attenuation accuracy. The ADRF5700 supports bidirectional operation and has a RF input power handling capability of 24 dBm average and 30 dBm peak for all attenuation states.

The ADRF5700 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 ADRF5700 can also operate with a single positive supply voltage (VDD) applied while the negative supply voltage (VSS) is tied to ground. In this operating condition, the small signal performance is maintained while the switching characteristics, linearity, and power handling performance are derated (see Table 2 in the data sheet).

The ADRF5700 RF ports are designed to match a characteristic impedance of 50 Ω. The ADRF5700 comes in a 20-terminal, 3.0 mm × 3.0 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 millimeterwave
  • Military radios, radars, electronic counter measures (ECMs)
  • Microwave radios and very small aperture terminals (VSATs)
