Sažetak

(ne postoji na srpskom)
We characterize the nonlinearities of our previously designed 10 W class-J power amplifier with a carrier at 1.5 GHz. We employ numerical simulations and real time adjacent channel power ratio (ACPR) measurements on the fabricated prototype. The measurements are performed for a wideband code division multiple access (WCDMA) signal with 10.5 dB peak-to-average power ratio (PAPR) and 3.84 MHz bandwidth.
