ANALOG DEVICES ADL8141-EVALZ

ADL8141-EVALZ is an evaluation board to evaluate the ADL8141 GaAs, pHEMT, MMIC, low noise amplifier, 14GHz to 24GHz. This is a 4-layer printed circuit board (PCB) fabricated from 8 mil thick, Rogers 4003C and Isola 370HR, copper clad, forming a nominal thickness of 62mils. The RFIN and RFOUT ports on the ADL8141-EVALZ are populated with female coaxial 2.4mm connectors, and the corresponding RF traces have a 50 ohm characteristic impedance. The ADL8141-EVALZ is populated with components suitable for use over the entire -40°C to +85°C operating temperature range of the ADL8141. To calibrate board trace losses, a through calibration path is provided between the J1 and J2 connectors. J1 and J2 must be populated with 2.4mm RF connectors to use the through calibration path.
