A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the edge of the board to minimize signal loss. A 50-ohm microstrip transmission line should be used to connect the device to the antenna.
The device requires a 3.3V power supply and a bias current of 10mA. A voltage regulator and a bias resistor network can be used to ensure proper biasing. The bias voltage should be applied to the VCC pin and the bias current should be set using a resistor divider network.
The ATN3590-10 can handle up to 2W of continuous wave (CW) power. However, the device can handle higher peak powers for short durations. It's recommended to derate the power handling capability based on the operating frequency and duty cycle.
Use a spectrum analyzer to measure the output power and frequency of the device. Check the bias voltage and current to ensure proper operation. Verify that the input signal is within the recommended power range. Use a thermal camera to check for overheating issues.
The device should be stored in a dry, cool place away from direct sunlight. Avoid touching the device pins to prevent electrostatic discharge (ESD) damage. Use an anti-static wrist strap or mat when handling the device. Follow the recommended soldering profile to prevent thermal damage.
