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 reflections. A 50-ohm microstrip transmission line should be used to connect the device to the antenna.
The device requires a single 3.3V power supply. A 10uF capacitor should be connected between the VCC pin and the GND pin to filter out noise. Additionally, a 1kohm resistor should be connected between the VCC pin and the EN pin to ensure proper biasing.
The device is rated for operation from -40°C to +85°C. However, the optimal operating temperature range is between 0°C to 70°C for maximum performance and reliability.
Use a spectrum analyzer to check the transmitted signal for spectral purity and power. Verify that the device is properly biased and that the PCB layout is correct. Check for any signs of overheating or physical damage to the device.
Yes, the device can be used in a multi-module configuration. However, each module should have its own power supply and biasing circuitry. The modules should be spaced at least 10mm apart to minimize electromagnetic interference.
