This presentation will discuss the rationale behind the adoption of Si, GaAs and the GaN technologies for use in downstream output stage high power gain blocks. Innovation in this field has been driven by demand for wider bandwidth, higher linear output power capabilities and improved efficiency to help reduce power consumption. We will look at how new semiconductor and packaging technologies meet the current and future demands of DOCSIS 3.1 networks. The presentation will assess the qualitative and quantitative potential of new technologies and examine the challenges related to the development of distortion test systems to understand the impact of DOCSIS 3.1 testing up to 1.2GHz and beyond.
