Product Details
●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.
