“…Irbid, Jordan Andrawes@ieee.org Figure 1 the Volterra series block diagram [10] In [11,12], the simple merit figures, such as the Intermodulation distortion (IMD) and the 1dB compression point, are inadequate to describe the nonlinear systems performance. The Inter-Modulation Distortion (IMD) can be defined as the signals amplitude modulation which includes different frequencies in a nonlinear system.…”

The modern information technology designers are working to increase the performance of any system by reducing the effects of distortion through determining the type of the system first, and then reducing the distortion. Multi-tone analysis of nonlinear systems contributes to understand distortion and the mechanism through which distortion is introduced in communication signals. This paper illustrates the performance of Multi-tone in nonlinear systems.

“…For small-signal RF excitations, the case of most practical significance in mixers, time-varying Volterra-series analysis has been proven to constitute an accurate and simple tool for IMD calculations [6]. Nevertheless, and to the authors' knowledge, most published works in FET mixers have dealt with simple (one-or twotone) RF signals [7], [8].…”

This paper presents a direct and robust analysis technique for evaluating nonlinear distortion phenomena in FET mixers excited by multitone signals. Time-varying Volterra-series analysis has previously been proven to be appropriate for small-signal intermodulation-distortion calculations in mixers excited by simple RF signals. Spectral convolutions of the suitably mapped control voltages are introduced in this paper in order to solve the nonlinear current source calculations for narrow-band modulated or broad-band multicarrier RF signals. Simulations and measurements of a properly characterized resistive mixer validate the accuracy of this direct and noniterative analysis tool for spectral regrowth and noise-power-ratio prediction in such applications.

“…Recently, some millimeter-wave ICs using flipchip bonding technology have been proposed to achieve cost reduction goals [2]- [4]. By combining of flipchip GaAs Gunn diodes and flipchip bonding technology onto AIN substrates, these problems of the millimeter-wave oscillator have been solved [5].…”
