On the antenna outputs I&#39;ve used the discrete component balanced to unbalanced circuit shows in the reference design, and I&#39;m including pads for an additional shunt capacitoren-USTelligent Community 13Mon, 05 May 2014 07:32:41 GMThttps://devzone.nordicsemi.com/thread/9853?ContentTypeID=1Mon, 05 May 2014 07:32:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ec091531-59e1-4057-af70-f7e6b6b18a03FormerMember<p>Hello,</p> <p>Yes, the attenuation network should be placed immediately after the balanced to unbalanced conversion circuit, followed by the calibration/tuning shunt capacitor.</p> <p>Regards, Kristin</p><div style="clear:both;"></div>
