https://devzone.nordicsemi.com/f/nordic-q-a/848/antenna-impedanceHello, I am currently using nRF24L01P with TI CC2591 in my RF module product. I have a doubt that need your help to clarify. Does the antenna impedance given in the datasheet (page 15) 15+j88 ohms refer to single ended or balanced impedance?en-USTelligent Community 13Fri, 08 Nov 2013 10:11:14 GMThttps://devzone.nordicsemi.com/thread/4171?ContentTypeID=1Fri, 08 Nov 2013 10:11:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:db424ff0-a1fe-4412-8b34-971af1e88e68Patrick Go<p>Thank you!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4170?ContentTypeID=1Thu, 07 Nov 2013 16:34:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:865a7cb6-6e24-41e8-94ac-2f599a627f78H&#229;kon Alseth<p>Hi,</p> <p>The impedance of the antenna should ideally be 50 ohm @ 2.4GHz.</p> <p>The impedance from the datasheet is the optimal load for the ANT1/ANT2 pins (ie: the BALUN load).</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
