Design & Engineering

Engineering excellence has been a tradition at Marport C-Tech for over 30 years in the design, development and integration of our products, as well as products designed and developed to customer specifications. Our experience in all of the critical areas allows us to take a product from initial concept through design, breadboarding, prototyping, manufacture and test.

We have demonstrated our expertise in many areas including:

Electronic Circuit Design - Analog Electronics

• Low Level Signal Conditioning
  • low-noise preamplifiers and bandpass filter arrays for capacitive sensors operating up to 500 kHz
  • variable gain control amplifer arrays
• Pulsed Power Amplifiers
  • pulsed linear and switched mode power amplifier arrays for complex loads providing up to 2.2 kw per channel and operating up to 500 kHz
• Analog to Digital Converters
  • multi-channel analog to digital conversion operation to 16 bits at 1.5M samples/sec
• Power Supplies
  • custom switching power supply assemblies to 1 kW operating to 1 MHz
  • custom power supplies for low-noise applications
