The progress in modern radio frequency (RF) and microwave telecommunications demands and relies on similar advancements in associated component- and system-level characterization that, in turn, depend upon the fundamental electrical metrology. In this thesis, a superconducting Josephson junction (JJ) technology was substantially improved to demonstrate new microwave voltage sources of unprecedented stability, as well as to significantly improve the state of the art. First, the cryogenic characterization of a Josephson junction comb generator was performed to analyze the nonlinear dynamics of the JJs and compared with simulations. Second, I demonstrated a new digital signal processing technique to equalize the multi-decade-bandwidth drive-current pulses required for the operation of superconducting JJ-based microwave voltage sources. Third, the design and on-wafer measurements of new over-a-decade bandwidth integrated analog signal processing devices -- room-temperature Gallium Arsenide (GaAs) and Gallium Nitride (GaN) distributed amplifiers and cryogenic superconducting Niobium-on-Silicon (Nb-on-SI) diplexers -- were demonstrated. Fourth, new RF Josephson Arbitrary Waveform Synthesizer (RF-JAWS) superconducting integrated circuits were designed and measured on-wafer in the liquid-helium environment using a new two-step cryogenic scattering-parameter calibration. Fifth, new characterization techniques were shown to significantly simplify the drive- and bias-current optimization necessary to stabilize the RF-JAWS operation. Sixth, I demonstrated the first superconducting source of broadband multisine and modulated voltage waveforms that can be used, respectively, for calibrations of broadband microwave instrumentation and for nonlinear characterization of telecommunication links.
