ADL8142-EVALZ

ADL8142-EVALZ evaluation board for evaluating the ADL8142 GaAs, pHEMT, MMIC, low noise amplifier (23GHz to 31GHz). It consists of a 4-layer printed circuit board (PCB) fabricated from 8mil thick, Rogers 4003C and Isola 370HR, copper clad, forming a nominal thickness of 62 mils. The RFIN and RFOUT ports on the ADL8142-EVALZ are populated with 2.92mm, female coaxial connectors, and the corresponding RF traces have a 50 ohm characteristic impedance. The ADL8142-EVALZ is populated with components suitable for use over the entire -40°C to +85°C operating temperature range of the ADL8142. To calibrate board trace losses, a through calibration path is provided between the J1 and J2 connectors. J1 and J2 must be populated with RF connectors to use the through calibration path. Access the ADL8142-EVALZ ground path and VDD pin through the surface-mount technology (SMT) test point connectors, GND and VDD. A supplementary test point for VBIAS is included for simple access on the RBIAS pin.
