Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the DRA9114Y0L. The device should be placed near the antenna, and the PCB layout should minimize signal traces and vias to reduce noise and radiation.
To ensure reliable operation in high-temperature environments, it's essential to follow proper thermal design and management practices. This includes providing adequate heat dissipation, using thermal interface materials, and ensuring the device is operated within its specified temperature range (–40°C to +85°C).
Panasonic recommends using a monopole or dipole antenna with a length of λ/4 (quarter-wavelength) or λ/2 (half-wavelength) at the operating frequency. The antenna should be placed at least 10 mm away from the device and other metal components to minimize detuning and radiation pattern distortion.
To optimize power consumption, use the device's built-in power-saving features, such as the sleep mode and low-power modes. Additionally, optimize the system's firmware and software to minimize the device's active time and reduce the number of transmissions. Use a low-power oscillator and optimize the voltage regulator's efficiency to further reduce power consumption.
To ensure compliance with regulatory requirements, such as FCC, CE, and TELEC, follow the recommended testing and validation procedures outlined in the datasheet and application notes. This includes conducting radiated emission tests, conducted emission tests, and immunity tests, as well as performing functional and performance testing.
