ADL5321-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a single 5 V/300 mA supply. The 5 V supply should be connected to the test loops labeled VCC and GND. The RF input is applied to the SMA connector labeled RFIN. The RF output is available at the SMA connector labeled RFOUT. To facilitate tuning for different frequencies, the RF input and RF output traces are free of solder mask and have index markings for ease of component placement. The evaluation board ships with tuning components that are optimized for operation from 2500 MHz to 2700 MHz. The ADL5321 data sheet provides recommended tuning components for other frequencies.
