Time-division polynomial pre-distorter for linearisation of 1.5 T MRI power amplifier

Autor: Ming Hui, Meng Zhang, Xingang Zhang, Xiaowei Zhu, Xiupu Zhang, Jiali Cheng

Publikováno v: The Journal of Engineering (2017)

A time-division polynomial (TDP) model is proposed for modelling and linearising a 1.5 T magnetic resonance imaging (MRI) power amplifier (PA) with strong non-linearity in high input signal dynamic range. In order to demonstrate the merit of this non

Class-F microwave amplifier in the S-band

Autor: Martinić, Matko

U ovom radu su opisani koraci dizajniranja F klase pojačala. Pojačalo je dizajnirano da tako da radi na frekvenciji od 2 GHz-a s ulaznom snagom od 5 dBm-a. Transistor je izmjeren i uspoređen s modelom u ADS-u. Simulacije u ADS-u su provedene bez d
