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 provide the required bias voltage and current. The bias voltage should be decoupled with a 10uF capacitor to ensure stability.
The ATN3580-10 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 they are within the recommended range. Verify that the input and output impedances are matched to 50 ohms. Use a thermal camera to check for overheating issues.
Yes, the ATN3580-10 can be used in a push-pull configuration to achieve higher output power and improved linearity. However, the device should be properly matched and biased to ensure optimal performance.
