<h3 id="external-pa-tx-power-curve">External PA / TX power curve</h3>
<p>For a board with an always-on external power amplifier after the SX1262. Both
flags are needed together; leave them unset on a bare-SX1262 board.</p>
<table>
<thead>
<tr>
<th>Flag</th>
<th>Meaning</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>LORA_TX_POWER=&lt;dBm&gt;</code> / <code>MAX_LORA_TX_POWER=&lt;dBm&gt;</code></td>
<td>Default and ceiling for the TX power the app/CLI may request. The SX1262 alone tops out at 22; a board with a PA sets these to what the PA really delivers (the GAT562 30S sets 30).</td>
</tr>
<tr>
<td><code>NUM_PA_POINTS=&lt;n&gt;</code> + <code>TX_GAIN_LORA=&lt;g0,g1,…&gt;</code></td>
<td>The PA's measured gain in dB for each SX1262 register setting <code>0 … n-1</code>. Requesting <em>X</em> dBm picks the lowest register setting whose <code>setting + gain</code> reaches <em>X</em>, clamped at the last entry once the PA saturates — so the reported power matches the radiated one. A request below the PA's floor gain still radiates at that floor, and the value stored/reported back is the power actually applied.</td>
</tr>

<p>The GAT562 30S uses the vendor-measured 869 MHz curve from
<a href="https://github.com/meshtastic/firmware/pull/11212">meshtastic/firmware#11212</a>.
Note the on-device <strong>Settings › Radio › TX Pwr</strong> row is still capped at 22 dBm;
values above that are set from the phone app or the CLI.</p>
