https://devzone.nordicsemi.com/f/nordic-q-a/1242/differential-transmission-line-impedance-matchingHi, We are trying to reuse the RF frontend design provided in reference design of PCA10000-nRF51822 Development Dongle 2_0. But because we have different board thickness, and different manufacture capability, how to control the differential transmissionen-USTelligent Community 13Tue, 04 Feb 2014 16:05:50 GMThttps://devzone.nordicsemi.com/thread/5739?ContentTypeID=1Tue, 04 Feb 2014 16:05:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2ee65c09-84d0-4eea-9a30-ad3ba4b255ceFormerMember<p>Hello,</p> <p>For PCB thicknesses of 0.8 mm to 1.6 mm there are hardly any differences, so it is not necessary do any changes to the width of the transmission line. What is important is to keep the length of the transmission lines as short as possible, in order to decrease the series inductance due to the length of the transmission lines and the capacitance to ground.</p> <p>Regards, Kristin</p><div style="clear:both;"></div>
