DLVA Grabs 0.5 to 2.0 GHz

June 2, 2015

This rugged DLVA provides a wide logging range from 500 MHz to 2 GHz.

Model GMDA-D1007 is an extended-range detector-log-video amplifier (DLVA) with frequency range of 0.5 to 2.0 GHz. It features a signal logging range of -60 to +7 dBm with tangential signal sensitivity (TSS) of -65 dBm. It delivers logging linearity of ±1.5 dB at room temperature and ±2.0 dB over the full operating temperature range of -54 to +85°C. The amplifier can handle input power to +23 dBm CW and provides +2.5 VDC maximum output voltage. The DLVA operates with video load impedance of typically 75 Ω and draws 300 mA at +12 to +15.5 VDC. Built to MIL-STD-202F, the DLVA achieves video rise time of 30 ns and recovery time of 1 μs, with maximum throughput time of 30 ns.
