ADRF5721BCCZN

ADRF5721 is a silicon, 4bit digital attenuator with a 30dB attenuation control range in 2dB steps. This device operates from 9KHz to 40GHz with better than 3.4dB of insertion loss. The ATTIN port of the device has a radio frequency (RF) input power handling capability of 26dBm average and 30dBm peak for all states. It requires a dual supply voltage of +3.3V and -3.3V. This device features serial peripheral interface (SPI), parallel mode control, and complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatible controls. It is pin compatible with the ADRF5731, the fast switching version, which operates from 100MHz to 40GHz. It is used in application such as industrial scanners, test and instrumentation, cellular infrastructure: 5G millimetre wave, military radios, radars, electronic counter measures (ECMs), microwave radios and very small aperture terminals (VSATs) etc.
