SI4438-C2A-GMR Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces as short as possible and use 50-ohm impedance matching to minimize signal reflections.
-
Use a 1/4 wavelength monopole antenna or a dipole antenna with a 50-ohm impedance. The antenna should be placed at least 10 mm away from the PCB edge and other components to minimize interference.
-
The maximum transmit power is +20 dBm (100 mW) with a 50-ohm load. However, the actual transmit power may vary depending on the antenna design and the operating frequency.
-
Use the device's built-in frequency synthesizer and the SPI interface to control the frequency hopping sequence. The device can hop between 100 channels in the 2400-2483.5 MHz frequency band.
-
The transmit latency is typically around 2-3 ms, while the receive latency is around 1-2 ms. These values may vary depending on the system design and the operating frequency.
