ADRF5731-EVALZ

ADRF5731-EVALZ is an evaluation-board for ADRF5731 silicon, 4bit digital attenuator with a 30dB attenuation control range in 2dB steps. The ADRF5731-EVALZ is a 4-layer evaluation board. Each copper layer is 2.2mil (1.5oz) 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 12mil Rogers RO4003, offering optimal high frequency performance. The middle and bottom dielectric materials provide mechanical strength.

• Overall board thickness is 62mil, which allows 2.4mm RF launchers to be connected at the board edges
