Abstract :
A completely new family of Radio Systems has been developed to meet the increasing demand for low cost, easily deployable systems with high capacity transmission. 128 QAM modulation scheme has been chosen for these systems and a new family of transmit and receive microwave modules has been developed to support with high linearity, high output power and low noise the performances of the complete system. The modules cover frequency bands from 6 to 38 GHz.
