https://devzone.nordicsemi.com/f/nordic-q-a/2566/adding-a-pa-to-the-nrf51822Howdy all, Has anyone added an external power amplifier to the nRF51822? From what I recall the BLE spec allows for 10mW output power (well, 10mW would be the maximum for global acceptance -- there are some country related exceptions that would allowen-USTelligent Community 13Thu, 16 Jul 2015 01:39:58 GMThttps://devzone.nordicsemi.com/thread/10199?ContentTypeID=1Thu, 16 Jul 2015 01:39:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bd281b9c-dfe4-4249-910b-909c93f0b246abbes<p>Hi all I need to increase rf power. What about a skywork Amplifier ? if there is any amplifier circuit please tell me about it and inform me about the pin connection . thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/10198?ContentTypeID=1Fri, 23 May 2014 12:47:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:888148c4-1291-4cc6-9b8d-ff0b0ff52e11Marc Nicholas<p>Hi Karim,</p> <p>Haven&#39;t gotten too far with this yet. One of the challenges is that traditional Bluetooth LNAs/PAs are not duty cycle optimized for BLE and waste too much energy.</p> <p>I think you&#39;re also finding the same and want to control the PA when the radio is in use via GPIO?</p> <p>Cheers,</p> <p>-m</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/10197?ContentTypeID=1Fri, 23 May 2014 12:44:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d3808d4-c116-4fcd-82f2-913c4fb47966Karim Ladha<p>Did you find an answer to your question? I also need to do this and to be successful we will need the external PA control signals to be routed to i/o pins on the device. Have you found a way to route these signals to the pins yet? Thanks Karim</p><div style="clear:both;"></div>
