ADL8140-EVALZ Evaluation Board for ADL8140

Analog Devices ADL8140-EVALZ Evaluation Board for ADL8140 is a 4-layer printed circuit board (PCB) fabricated from 8mil thick, Rogers 4003C and Isola 370HR, copper clad, forming a nominal thickness of 62mils. The RF_IN and RF_OUT ports on the ADL8140-EVALZ are populated with female coaxial 2.9mm connectors, and the corresponding RF traces have a 50Ω characteristic impedance. The ADL8140-EVALZ is populated with components suitable for use over the entire -55°C to +125°C operating temperature range of the ADL8140. A thorough calibration path is provided between the J1 and J2 connectors to calibrate board trace losses. J1 and J2 must be populated with 2.9mm RF connectors to use the through calibration path.
