The SDL-328 from Microphase Corporation is a Successive Detector Log Video Amplifier (SDLVA) that operates from 2 to 8 GHz. It has a 25 mV/dB log slope with a log range from -70 to 0 dBm and a TSS (Tangential Signal Sensitivity) of -73 dBm. This DLVA has a maximum rise time of 10 ns with a maximum delay of 10 ns and a recovery time of 80 ns. It can handle a video load of 93 Ohms and requires a DC supply of 12/-12 V. The DLVA has a VSWR of 2:1 and a pulse width range from 20 ns to CW.
The SDL-328 has a proprietary Differential Schottky Detector-Limiter that operates over narrow portions of their dynamic ranges to provide 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. It is available in a package that measures 3.5 x 2.6 x 0.5 inches and has SMA and pins connectors.
