GENERAL DESCRIPTION

The ADRF5720 is a silicon, 6-bit digital attenuator with 31.5 dB

attenuation control range in 0.5 dB steps.

The ADRF5720 is pin-compatible with the ADRF5730, the fast

switching version, which operates from 100 MHz to 40 GHz.

This device operates from 9 kHz to 40 GHz with better than 4.5 dB

of insertion loss and excellent attenuation accuracy. The ATTIN

port of the ADRF5720 has a radio frequency (RF) input power

handling capability of 27 dBm average and 30 dBm peak for all

states.

The ADRF5720 RF ports are designed to match a characteristic

impedance of 50 Ω. For wideband applications, impedance

matching on the RF transmission lines can further optimize high

frequency insertion loss, return loss, and attenuation accuracy

characteristics. Refer to the Electrical Specifications section, the

Typical Performance Characteristics section, and the Applications

Information section for more details.

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 complementary metal-oxide

semiconductor (CMOS)-/low voltage transistor to transistor

logic (LVTTL)-compatible controls.

The ADRF5720 comes in a 24-terminal, 4 mm × 4 mm, RoHS

compliant, land grid array (LGA) package and operates from

−40°C to +105°C.
