A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the EMI9408MUTAG close to the antenna and use a short, direct connection to minimize radiation.
Use a network analyzer to measure the antenna's impedance and adjust the matching network accordingly. The EMI9408MUTAG's output impedance is 50 ohms, so a conjugate match is recommended.
The EMI9408MUTAG can handle up to 30 dBm (1W) of continuous power. However, it's recommended to derate the power handling based on the operating frequency, temperature, and other environmental factors.
Use the shutdown pin to disable the device when not in use. Additionally, optimize the output power and adjust the bias voltage to minimize current consumption.
The EMI9408MUTAG operates from -40°C to 85°C. However, the device's performance and reliability may degrade at extreme temperatures.
