Technical Feature Design of a Predistortive High Power Amplifier Using Carrier Complex Power Series Analysis In this article, a new carrier complex power series for linearizing the distortion effects of a high power amplifier (HPA) is proposed. The amplitude (AM-to-AM) and phase (AM-to-PM) nonlinear characteristics of the HPA are...

Technical Feature The Use of Intermodulation Tables for Mixer Simulations The use of intermodulation table (IMT) files can lead to accurate prediction of the output frequency content of an up-converting or down-converting mixer in system simulations. For best results, custom IMT files should be constructed from mixer output spectrum...

Technical Note Output Power Improvement of a Push-push FET DRO by Using an Additional DR In this article, the output power level and phase noise properties of nine conventional push-push dielectric resonator oscillators (DRO) have been experimentally investigated while adding an identical dielectric resonator (DR) at the drain ports....
