https://devzone.nordicsemi.com/f/nordic-q-a/26863/nrf2460-external-paThe product description says the nRF2460 has &quot;Support for external PA&quot;. Since this chip does not present separate TX and RX RF terminals, and no apparent TDD output logic signal, how would this be done? Any examples out there?en-USTelligent Community 13Tue, 14 Nov 2017 11:06:44 GMThttps://devzone.nordicsemi.com/thread/105588?ContentTypeID=1Tue, 14 Nov 2017 11:06:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:56568db0-c6ae-4f6e-9435-ca85d709b0ecovrebekk<p>Hi</p> <p>You can use the VDD_PA signal to control an external PA.</p> <p>It will go high (1.8v) approximately 50us before the TX packet is sent, and will be low otherwise.</p> <p>Best regards<br /> Torbjørn</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/105589?ContentTypeID=1Mon, 13 Nov 2017 21:14:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fcbc9add-23ee-440c-88ae-aba635ba43bfAmbystomaLabs<p>The standard approach for adding an external PA to a wireless SoC is with a front end module (FEM). The FEM will have internal switches to select either Tx or Rx modes and may have an LNA in addition to a PA. Generally the mode selection for the FEM is done through GPIO, though some Nordic devices accomplish this through the VCC_PA connection.</p> <p>Probably the most popular company for Bluetooth FEM&#39;s right now is Skyworks Inc. They have a relatively large selection of Bluetooth FEM&#39;s.</p> <p>You can find them at: <a href="http://www.skyworksinc.com">http://www.skyworksinc.com</a></p><div style="clear:both;"></div>
