Microphase Introduces Successive Detection DLVA (SDL Series) SDL-328
2.0-8.0 GHz and the SDL - 3618 6.0-18.0 GHz
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.
