The ADRF5720 is an ultrawideband, high accuracy 6-bit silicon digital attenuator, operating from 9 kHz to 40 GHz with 31.5 dB attenuation control range in 0.5 dB steps.
The ADRF5720 offers excellent attenuation accuracy and high linearity with maximum input power handling of 27 dBm for all states.
The ADRF5720 requires dual supply voltages, 3.3 V and −3.3 V. The device incorporates a driver that supports TTL-/CMOS-compatible serial and parallel controls.
The ADRF5720 is unidirectional, with an radio frequency (RF) input and output internally matched to 50 Ω. It comes in a RoHS compliant, 4 mm × 4 mm, 24-lead land grid array (LGA) package.
