RF electronic design

Protech designs and develops circuits and electronic equipment for radio frequency (RF) applications:

  • Low noise RF gain blocks, hi-linearity, wideband
  • RF driver amplifiers, RF Power Amplifiers
  • RF power generators for plasma applications
  • HF-VHF-UHF band TX/RX modules
  • FM/DAB/DAB+ receivers
  • ROF (radio-over-fiber) fiber optic systems
  • SDR (Software Defined Radio) with firmware and application software development
  • Antenna design and matching

ROF (RF over fiber) applications

We develop wideband optical links for ROF applications, customized according to the requirements of the specific application.

The ROF link converts the incoming RF signal into an optical signal on single-mode fiber, allowing it to travel long distances (10-100km) without degrading quality or intelligibility. A typical application is, for example, transferring the signal from a satellite antenna to a remote area where the receiving equipment is located.

Thanks to CWDM (Coarse Wavelength Division Multiplexing) technology, it is also possible to use a single optical fiber to send multiple wavelengths, enabling more compact links and minimizing fiber usage.

Applications

SKA-Low AAVS 2.0 antenna station

"Made in Italy" antenna forest for SKA

The installation of the first Ska-Low Aavs 2.0 prototype station has just been completed at the Murchison Radio Observatory, in the Australian outback, built by engineers and technicians from the National Institute of Astrophysics, the National Research Council, and numerous Italian companies, including Protech.
