TRF6901PTR datasheet by Texas Instruments

TRF6901PTR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF signal traces short and away from the digital signals. Use a common mode filter or a pi-filter to reduce EMI.
• How do I optimize the TRF6901PTR for low power consumption?
  Use the lowest possible supply voltage (1.8V), reduce the transmit power, and use the built-in power-saving features like the low-power mode and the automatic power control (APC).
• What is the maximum data rate achievable with the TRF6901PTR?
  The maximum data rate is 2 Mbps, but it depends on the modulation scheme, frequency, and transmission mode used. For example, in OOK mode, the maximum data rate is around 1 Mbps.
• How do I implement frequency hopping with the TRF6901PTR?
  Use the built-in frequency synthesizer and the PLL calibration feature to implement frequency hopping. The device supports up to 16 frequency channels, and the frequency hopping sequence can be programmed using the SPI interface.
• What is the range of the TRF6901PTR, and how can I improve it?
  The range of the TRF6901PTR depends on the transmission power, antenna design, and environment. To improve the range, use a high-gain antenna, optimize the transmission power, and reduce interference from other devices.
