A miniature SDLVA provides fast pulse detection and processing with a 70-dB dynamic range from 0.25 to 6.0 GHz.
Successive-detection log-video amplifiers (SDLVAs) such as the model SDLVA-250M6G-CD-1 help process pulsed and continuous signals over a wide dynamic range. This particular unit operates from 0.25 to 6.0 GHz with a dynamic range from -70 to 0 dBm and ±2.5-dB worst-case logarithmic linearity. It features a fast rise time of 10 ns or less and recovery time of less than 60 ns. Supplied in a compact housing measuring just 3.2 x 1.8 x 0.4 in. with female SMA connectors, the SDLVA achieves typical tangential signal sensitivity (TSS) of -73 dBm and exhibits maximum VSWR of 2.0:1. It can handle input power levels as high as +17 dBm and draws nominal current of 350 mA at +15 VDC and 180 mA at -15 VDC. The amplifier, which is designed for operating temperatures from -40 to +70°C, meets the applicable requirements of MIL-STD-202F for humidty, shock, vibration, and altitude.
