A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF signal traces as short as possible and away from the power plane. Use a common mode filter or a ferrite bead to reduce noise and EMI.
Optimize the output power by adjusting the input power, bias voltage, and load impedance. Ensure the device is operated within the recommended operating conditions and that the output is properly matched to the load.
The maximum operating temperature range for the TRF3750IPWR is -40°C to 85°C. However, the device's performance may degrade at higher temperatures, so it's essential to ensure proper thermal management.
To reduce the noise figure, ensure the device is operated at the recommended bias voltage and current. Use a low-noise power supply, and add noise-reducing components such as capacitors or resistors to the circuit. Optimize the PCB layout to minimize noise coupling.
The recommended input impedance is 50 ohms, and the recommended output impedance is also 50 ohms. Ensure the input and output are properly matched to the device to achieve optimal performance.
