The ADRF5730 is a silicon, 6-bit digital attenuator with 31.5 dB attenuation control range in 0.5 dB steps.
This device operates from 100 MHz to 40 GHz with better than 4.8 dB of insertion loss and excellent attenuation accuracy. The ADRF5730 has a radio frequency (RF) input power handling capability of 27 dBm average and 30 dBm peak for all states.
The ADRF5730 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 ADRF5730 is pin-compatible with the ADRF5720 low frequency cutoff version, which operates from 9 kHz to 40 GHz.
The ADRF5730 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.
The ADRF5730 comes in a 24-terminal, 4 mm × 4 mm, RoHS-compliant, land grid array (LGA) package and operates from −40°C to +105°C.

Markets & Technology
Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The ADRF5730-EVALZ is a 4-layer evaluation board. Each copper layer is 0.7 mil (0.5 oz) and separated by dielectric materials.
All RF and dc traces are routed on the top copper layer whereas the inner and bottom layers are grounded planes that provide a solid ground for the RF transmission lines. Top dielectric material is 8 mil Rogers RO4003, offering optimal high frequency performance. The middle and bottom dielectric materials provide mechanical strength. The overall board thickness is 62 mil, which allows 2.4 mm RF launchers to be connected at the board edges.
Tools & Simulations
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
