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.



Frequency Discriminator translates incoming RF/Microwave signals into a monotonic output voltage that is proportional to the RF/Microwave frequency. Accurate frequency information can then be derived from the Output Voltage because a Delay Line Frequency Discriminator takes the Input RF/Microwave Signal and produces two RF/Microwave Signal components that have a phase shift that is proportional to the original input frequency at fixed power input levels. By summing the two signal components together and then using detection techniques produces a detected Output Voltage that is frequency dependant. Therefore as the input RF/Microwave Signal frequency is varied so does the output voltage of the Delay Line Frequency Discriminator.
