This paper presents an extraction procedure and a new modeling approach for behavioral model approximations of mixed-signal digital to analog integrated transmitters. An explanation on how to extract the seek kernels for a specific device is shown, including a new procedure for phase synchronization. The characterization procedure is applied to a real device. The simulation outcomes using the extracted model are then compared with real modulated signal measurements. The obtained results validate the proposed strategy and enhance the utility of the framework.Index Terms-Digital-to-analog converter (DAC), instrumentation and measurement, integrated microwave circuits and systems, mixed signal, RF device modeling and characterization, softwaredefined radio (SDR). 0018-9480

“…The VSA consists of an optional bandpass filter, a downconverter and an analog-todigital converter. These components cause linear and nonlinear distortion in the signal measurement as demonstrated in, e.g., [1] and [2]. Assuming the instrument is operated in a linear voltage regime, linear distortion dominates the measurement and can be quite significant [1], [2].…”

Abstract-We propose a compact and low-cost waveform source that can be used to calibrate the magnitude and phase response of vector receivers over a bandwidth as large as a few gigahertz. The generator consists of a broadband comb generator followed by a filter and amplifier. As a demonstration, we constructed and calibrated a source suitable for calibrating vector signal analyzers operating between 43 GHz and 46.5 GHz. We then used the source to characterize the response of a commercially available vector signal analyzer. We compared the result with calibrations performed with a general-purpose source.

“…Besides, time-domain (TD) measurement techniques are also reported as an interesting alternative for FTD measurements [5], [16]- [19]. Dunsmore describes in [4] a vector mixer calibration (VMC) technique, and makes a comparison between different vector characterization methods for mixer measurements when using general-purpose VNAs [7].…”

In this paper, the authors report on a useful technique for accurately characterizing frequency translating devices below the 10-MHz starting frequency point of general-purpose vector network analyzers (VNAs). A procedure based on a four reciprocal mixers setup is proposed here to overcome this physical boundary. The complete system setup and measurement technique is explained in detail and precise considerations are mentioned for the correct follow-up of the procedure. The presented technique has been used here to characterize a frequency generation and upconverter payload used in actual space-borne global navigation satellite systems. Characterization results obtained by following the proposed technique are compared with experimental data obtained with a low-frequency VNA able to nominally operate below 10 MHz.
