Raw RF measurement data for an active quadrature zero-IF front end with RFSoC-based local-oscillator synthesis (500-6250 MHz)

Complete raw measurement data supporting the article "Design and Experimental Characterization of an Active Quadrature Zero-IF RF Front End with RFSoC-Based LO Synthesis and Conditioning for Wideband Spectrum Analysis".

The dataset comprises more than 120,000 measurement records acquired across three complementary experimental setups characterizing a five-path active zero-IF quadrature RF front end co-designed with the RealDigital RFSoC 4x2 platform over 500-6250 MHz. Each frequency point is the result of three repeated measurement sets.

Setup 1 - swept single-tone characterization (Agilent E8257D signal generator + Keysight FieldFox N9916A spectrum analyzer): conversion gain, input and output 1 dB compression points, noise figure by the gain method, I/Q gain imbalance, second-order harmonic distortion.

Setup 2 - swept two-tone characterization (Rohde & Schwarz SMCV100B + FieldFox N9916A): input- and output-referred third-order intercept points.

Setup 3 - frequency-converting vector network analysis with embedded local oscillator (Rohde & Schwarz ZNA26): conversion gain, compression points, I/Q gain imbalance, quadrature phase error, image rejection ratio, group delay and phase delay.

Files are provided in Microsoft Excel (.xlsx) format, one file per measured parameter and setup. See README.md for the column layout and measurement conditions of each file.
