This series of microwave links have been designed according to cutting-edge concepts and technologies for the transmission of high-quality digital signals. The system allows the transmission and reception of a stream of 34 Mbits/s (up to 155 Mbits/s optional) in both point-to-point applications and multi-hop connections.

The excellent spectral purity and extremely low noise of conversion oscillators allows optimal BER levels and the use of QPSK or QAM modulations. The modulators and demodulators include an internal network adapter in order to permit a direct connection to digital transmitters or other serial units thanks to its ASI interfaces.

These microwave links are available in different frequency ranges from 1.4 to 24 GHz with different output powers both in the internal versions and those with external RF heads. In the latter case, the external head is connected to the internal console by means of a coaxial cable through which pass both the I.F. signal and the power supply. For particularly difficult connections, a series of external solid-state amplifiers, including high-power ones, is also available.
