ADRF5720BCCZN

ADRF5720 is a silicon, 6bit digital attenuator with 31.5dB attenuation control range in 0.5dB steps. This device operates from 9KHz to 40GHz with better than 4.5dB of insertion loss and excellent attenuation accuracy. The ATTIN port of the device has a radio frequency (RF) input power handling capability of 27dBm average and 30dBm peak for all states. It enquires 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 ADRF5730, 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.
