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. A 1kohm resistor should be connected between the EN pin and the VCC pin to enable the device.
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 spectrum and ensure it meets the required specifications. Check the device's power supply and biasing to ensure it is within the recommended range. Use a logic analyzer to check the device's control signals and ensure they are correct.
Yes, the AFBR-5805ATZ can be used in a multi-module MIMO system. However, each module should have its own antenna and the modules should be spaced at least 1/4 wavelength apart to minimize interference.
