February 5, 2009 - The Microphase SDL-Series SDLVAs combine the best
performance features of currently available successive Detection DLVAs and the conventional RF amplifier/Coupler
extended range designs. A novel and unusual approach halves the number of successive detection points, thus
simplifying gain and frequency compensation vs. temperature. The results improved linearity, frequency flatness
temperature stability and absolute accuracy. The key component of this design is a proprietary Differential
Schottly Detector-Limiter. These devices, operating over narrow portions of their dynamic ranges, provide both
low and high level video signals, which are then differentially-coupled to single, low-gain video amplifier
stages, enabling improved rise time and recovery time.
