Design Notes

For optimal RF performance, place the STA8090GATR close to the antenna and ensure a 50-ohm impedance-controlled trace for the RF input. Use a ground plane beneath the RF section and add decoupling capacitors (100nF and 10uF) near the VCC and VCC_RF pins. Follow STMicroelectronics' layout guidelines for the VFQFPN-56 package.

The STA8090GATR requires a clean 1.8V supply. Use a low-noise LDO to power the device and avoid sharing the supply with digital circuits that may introduce noise. Add a ferrite bead in series with the supply to filter high-frequency noise. The integrated LDO helps regulate internal voltages, but external decoupling is still necessary.

Ensure the antenna is properly matched and has a clear view of the sky for optimal signal reception. Avoid placing the device near sources of electromagnetic interference, such as switching regulators or high-speed digital lines. Also, verify that the UART/SPI/I2C lines are not routed near the RF input to prevent coupling.
