“…Surprisingly, not much research has been done on behavioral modelling of all-digital transmitters. Neural networks based behavioral ADT models were presented in [8]. Main deficiency of such black box modeling is the lack of insight into structure and internal dynamics of the nonlinear system being approximated.…”

In this paper an exact baseband equivalent model of a quadrature modulated all-digital transmitter is derived. No restrictions on the number of levels of a digital switched-mode power amplifier (SMPA) driving input, nor the pulse encoding scheme employed, are made. This implies a high level of generality of the proposed model. We show that all-digital transmitter (ADT) can be represented as a series connection of the pulse encoder, discrete-time Volterra series model of fixed degree and memory depth, and a linear timevarying system with special properties. This result suggests a new analytically motivated structure of a digital predistortion (DPD) of SMPA nonlinearities in ADT. Numerical simulations in MATLAB are used to verify proposed baseband equivalent model.Index Terms-Digital predistortion, all-digital transmitter, baseband equivalent model.

“…Microwave amplifiers add noise to the coveted signal delivering corruption of affectability, determination and signal quality in wireless systems. NF is usually decided without the carrier, yet it can likewise be acquired from AM or PM noise spectra and, along these lines, as an element of carrier level [4][5][6].…”

Abstract-In this paper, the test portrayal strategies of nonlinear measurements of wideband LNA exhibitions are simulated. Likewise, significance of the nonlinear estimations has been portrayed unmistakably with microwave LNA operating large signal analysis had been assessed. This work is endeavored to demonstrate the performances of the LNA with AM-AM, AM-PM measurements in points of interest and differentiating from the linear measurement regime. The most of the important aspects of LNA will be in linear measurements and furthermore to quantify nonlinear measurements accurately harmonic balance simulator is used. The harmonics up to order 3 and power characteristics are altogether shown with power swept variable. A simulation setup is made to measure the characteristics of LNA by using spectrum rectangular display type with power harmonic components. At last, author designed wideband LNA from the bandwidth 1 GHz to 5 GHz and elaborates how nonlinear measurements changed the way of LNA design to validate and development in microwave frequencies.
