Test equipment may perform radio-frequency testing on the NFC circuitry. During manufacture of an electronic device having the NFC circuitry, the test equipment may be placed into electrical contact with antenna feed terminals on the NFC circuitry prior to attaching an antenna to the feed terminals so that a conductive path is formed between the test equipment and an NFC transceiver on the NFC circuitry. Test signals may be conveyed between the test equipment and the NFC transceiver over the conductive path for characterizing the performance of the NFC circuitry. The conductive path may include an antenna impedance modeling circuit formed on a circuit board substrate that models the impedance of the antenna that is to be attached to the NFC circuitry to allow for suitable power transfer during testing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for performing radio-frequency testing on near-field communications circuitry","description":"An electronic device may be provided with near-field communications (NFC) circuitry for communicating with external equipment.
