This device operates from 9 k Hz to 40 GHz with better than 4.5 d B of insertion loss and excellent attenuation accuracy. The ATTIN port of the ADRF5720 has a radio frequency (RF) input power handling capability of 27 d Bm average and 30 d Bm peak for all states. The ADRF5720 requires a dual supply voltage of +3.3 V and - 3.3 V. The device Features serial peripheral interface (SPI), parallel mode control, and plementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-patible controls.
