This paper presents the design of a 5th-order analog predistorter using the inband intermodulation (IM) signals for predistortion of base-station high power amplifiers (HPAs) for the North American Digital Cellular (NADC) system. The predistorter employs two mixers with same configuration to generate 3rd-order intermodulation (IM3) products and 5th-order intermodulation (IM5) products, to suppress...
This paper presents the design of a 5th-order analog predistorter to suppress the 3rd-and 5th-order intermodulation distortion products (EVTDP3 and EVTDP5) at the output of a base-station power amplifiers (PAs). The predistorter consists of two mixers: one mixer generating the 3rd-order intermodulation (IM3) products and another mixer of same configuration generating the 5th-order intermodulation...
This paper presents the design of a circuit to generate 3rd- and 5th-order intermodulation (IM3 and IM5) products used for predistortion of base-station high power amplifiers (HPAs). The circuit employs a mixer constructed using two Schottky diodes as a nonlinear device to generate the IM3 products and another mixer of the same configuration to generate the IM5 products using the IM3 products generated...
