Products 

EPOS SA designs, produces and markets high performance/ high complexity electronic systems for filtering/amplification, digitization, processing and synthesis of signals in the IF, RF and microwave frequencies.
"EPOS SA" offers the following products:
  • Analog to Digital Converters
  • Wideband Digital Receivers
  • FFT Digital Signal Processors
  • Digital IF / RF synthesizers
  • Digital Radio Frequency Memories
These products are implemented in the form of 6U cPCI boards and provide extensive interconnection capabilities with each other. They can be utilized as stand alone products or as modules for larger systems targeted at defence industry or research applications.
