https://devzone.nordicsemi.com/f/nordic-q-a/44875/antenna-pin-impedanceHello, could you confirm the antenna pin impedance for the nRF52810QCAA is also 53 + j66 Ohms? Thank youen-USTelligent Community 13Thu, 02 Dec 2021 16:25:20 GMThttps://devzone.nordicsemi.com/thread/341748?ContentTypeID=1Thu, 02 Dec 2021 16:25:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:66d3b9f7-4a8c-47b2-8bcf-02873744d1e7Adam Varga<p><a href="https://devzone.nordicsemi.com/members/simonr">Simonr</a>, does this value differ for the&nbsp;<strong>nRF52832-QFAB </strong>or the&nbsp;<strong><span>nRF52832-CIAA-R7</span></strong>? Is there a reason why this value is not included in the datasheets?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/311306?ContentTypeID=1Tue, 25 May 2021 07:11:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5bbf1fe6-fe8a-49db-93bc-137152f4f302Simonr<p>Hi Luke</p> <p>The status is still the same. 53 + j66Ω is the recommended impedance to work with.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/311149?ContentTypeID=1Fri, 21 May 2021 22:56:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:95a3483f-c1a6-4da0-8b47-3121905c0f96LukeMills<p>Has there been any progress on this in the last 2 years?
