https://devzone.nordicsemi.com/f/nordic-q-a/30581/nrf52832-carrier-frequencyHello, when transmitting packets with nRF52832 is there any chance to keep the carrier frequency off until the first bit of the preamble is being sent? (The product specification implies that the carrier frequency is not on before the first bit, if theen-USTelligent Community 13Wed, 07 Mar 2018 11:44:14 GMThttps://devzone.nordicsemi.com/thread/123222?ContentTypeID=1Wed, 07 Mar 2018 11:44:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5f520266-3afa-4ad7-b399-a371fe6a66c4ovrebekk<p>Hi Lukas</p> <p>Sorry for the slow reply.&nbsp;</p> <p>There is no way to remove this carrier, no.&nbsp;</p> <p>The PLL has to lock onto the reference clock at full output power, or the frequency would shift when the PA was turned on.
