Implication

Experimental evaluation reveals direct sensitivity and impedance characterization in UHF RFID chips, suggesting simplified testing across various packaging types.

Key Points

To establish a direct and efficient measurement method for determining the sensitivity and threshold impedance of UHF RFID chips without custom impedance matching.
Coupled an RFID tester featuring variable output power and frequency with a vector network analyzer.
Connected chips directly to standard 50-ohm connectors to perform direct measurements without specialized matching networks.
Tested two commercial UHF Gen2 chips (NXP UCODE G2XM and Impinj Monza 2) in TSSOP packages and validated results with 50-ohm matched assemblies.
Direct measurement through standard 50-ohm connections successfully captured both threshold impedance and sensitivity parameters.
Verification using two 50-ohm matched chip assemblies confirmed measurement accuracy across tested devices.
The direct characterization approach demonstrated adaptability for alternate packaging formats including flip-chip and strap configurations.
