A new digital lookup table adaptive pre-distortion technique for power amplifier linearization is presented. This approach uses a multi-port receiver at linearization loop in place of a classic heterodyne receiver. The five-port receiver is implemented by use of the passive microwave circuits and detector diodes. The system is designed to satisfy 3G power amplifier specifications. The performance...
A new wide-band direct conversion receiver based on Five-port structure is presented that is very suitable for software radio applications. New five-port structure consists of five wideband power splitters and a 900 phase shifter, including a set of composite right/left-handed (CRLH) transmission line (TL) sections. As an example the transceiver is designed for covering three WiMAX frequency bands,...
A five-port Ka-band direct conversion receiver based on Six-port structures has been presented that is very suitable for software defined radio applications. An experimental prototype has been fabricated using microstrip components for 23-29 GHz frequency band. Simulation and measurement results are presented to validate the proposed approach. An exellent agreement shows the accuracy of the proposed...
