When testing or using, connect the antenna first, then power on to transmit the signal. 2. The module uses a high-gain, high-efficiency power amplifier. When the output power of SX1262 is +22dBm (max), the module output power is maximum. 3. Suggestion: Please give the internal PA stabilization time before transmitting data: For SX1262 chip, the recommended configuration value is >800us -![RampTime](./images/RampTime.jpg) + + ![RampTime](./images/RampTime.jpg) + 4. When the module is ready to transmit/receive data, you need to switch the RF Switch on the module to the transmit/receive channel in advance. This switch is a single-pole double-throw switch.
