A good PCB layout for the MAX2472EUT+T involves keeping the input and output traces short and separate, using a solid ground plane, and placing the device close to the antenna. A 4-layer PCB with a dedicated ground plane is recommended. Additionally, the device's exposed pad should be connected to a solid ground plane to reduce thermal resistance.
The choice of antenna depends on the frequency band, operating environment, and size constraints of your application. For the MAX2472EUT+T, a 50Ω antenna with a good impedance match is recommended. You can use a chip antenna, patch antenna, or a monopole antenna, and optimize its design using simulation tools or antenna design software.
The MAX2472EUT+T can handle a maximum input power of +20dBm (100mW) without damage. However, the device is designed to operate at a maximum output power of +15dBm (30mW) to ensure reliable operation and minimize the risk of overheating.
Impedance matching is critical for optimal performance of the MAX2472EUT+T. You can use a pi-network or a T-network topology with discrete components (inductors and capacitors) to match the device's output impedance to the antenna's input impedance. You can use simulation tools or impedance matching software to optimize the matching network design.
The MAX2472EUT+T has a thermal pad that must be connected to a solid ground plane to reduce thermal resistance. You should also ensure good airflow around the device, avoid blocking the thermal pad, and use thermal interface materials (TIMs) if necessary. The device's junction temperature should be kept below 150°C to ensure reliable operation.
