ADI ADRF5731BCCZN-R7

The ADRF5731 is a silicon, 4-bit digital attenuator with a 30 dB attenuation control range in 2 dB steps. This device operates from 100 MHz to 40 GHz with better than 3.5 dB of insertion loss. The ATTIN port of the ADRF5720 has a radio frequency (RF) input power handling capability of 26 dBm average and 30 dBm peak for all states. The ADRF5731 requires a dual supply voltage of +3.3 V and -3.3 V. The device features serial peripheral interface (SPI), parallel mode control, and complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL) compatible controls. The ADRF5731 is pin compatible with the ADRF5721 low frequency cutoff version, which operates from 9 kHz to 40 GHz. The ADRF5731 RF ports are designed to match a characteristic impedance of 50 Ω. The ADRF5731 comes in a 16-terminal, 2.5 mm×2.5 mm, RoHS compliant, land grid array (LGA) package and operates from -40°C to +105°C.
