Miniature Successive Detection Log Video Amplifier: SDLVAC-0120-70M

January 29, 2021

PMI Model No. SDLVAC-0120-70M is a miniature successive detection log video amplifier that operates over the 0.1 to 2.0 GHz frequency range. This unit has a dynamic range of 65 to 70 dB, a TSS of -67 dBm, and a nominal video bandwidth of 20 MHz.  This unit is designed using cutting edge GaAs technology, which provides stunning performance and reliability in a compact package making it an optimum solution for high speed channelized receiver applications. This unit offers typical fast rise time of <20 ns, rapid fall time of <25 ns, as well as superior delay time of 8 ns. The log slope is 25 mV/dB and the accuracy is less than ±1.0 dB over the -60 to 0 dBm power input range. Dynamic range can be extended to -65/+5 with log error of ±1.5 dB. Options are available with adjustable logging slope and DC offsets. Guaranteed rise times are less than 25 ns and maximum recovery times are less than 30 ns. Recovery time at lower power are faster. It is commercially screened and characterized from -55 °C to +85 °C.

 Sizes available are 0.395" x 0.280" x 0.090" or another customized configuration desired. https://www.pmi-rf.com/product-details/sdlvac-0120-70m
