ISO 9001:2000 Certified



Planar Monolithics Industries, Inc. is very proud to announce that effective December 17, 2003 PMI has become ISO 9001:2000 Certified for the following scope of registration: Research, Development, Custom Design and Manufacture of RF/ Microwave Components, Super Components and Subsystems, in the DC to 40 GHz Frequency Range.  Please click here to see PMI's ISO Certificate.



The Model TA-SDLVA-0120-70 Option 105F Log Amplifier and Threshold Detector operates over the 1.3 to 1.7 GHz Range.  These units have a Dynamic Range of 65 to 70 dB, and a TSS of -60 dBm.  Furthermore, these units are designed using cutting edge GaAs Technology which provides stunning performance and reliability in a compact package.  These units offer typical fast Rise Time of ≤20 nS, and a rapid Fall Time of ≤30nS.

The Log Slope is 30 mV/dB and the accuracy is less than 2.0 dB over the -60 to 0 dBm power input range.  The TA-SDLVA-0120-70 Option 105F Log Amp and Threshold Detector is commercially screened and characterized from -55C to +85C.  Sizes available are 3.75" x 1.50" x 0.50" or to any other customized configuration desired.
