This paper presents measurements of transresistance of the vortex flow transistor (VFT). These measurements were obtained at frequencies up to 500 MHz which was one-tenth of the transit time cutoff frequency. A signal tagging scheme was developed to detect these high-frequency signals that would otherwise be obscured by high crosstalk levels. The measured frequency response of the VFT indicates that the transresistance signal is present at frequencies greater than one-tenth of the transit time cutoff frequency. Thus, the VFT is a viable active device candidate for rf superconducting electronic systems.
