Widespread adoption of higher order modulation schemes, larger signal bandwidths and higher operating frequencies, to enable higher data throughput in communication links like 5G, places increasingly tough demands on the frontend. Signal fidelity is often enhanced with linearization.The greater number of RF chains and signal bandwidth in 5G Frontends mean that DPD (Digital Pre-Distortion) may no longer be the default linearization choice; 5G Frontends will be completely different from their 4G predecessors.The key metrics of Efficiency, Linearity, Bandwidth and Output Power remain, as does the question of how to optimally create the signal with just enough fidelity and power, with a minimum of wasted power. The solution set to that question, however, has never been greater.Amongst other topics, this White Paper, (i) proposes a classification of Linearization schemes, (ii) introduces the hard limiter, (iii) illustrates linearization of an exemplary mmWave PA using non-DPD techniques, and (iv) introduces a class of linearized transmitters that create their signal and linearity from efficiently generated components.

Long Term Evolution (LTE) technology has become the technology of choice for keeping up with the requirement of higher throughput in mobile communication in bands below 6 GHz. It is expected that within the next decade LTE will become the primary commercial standard. LTE is often used to broadcast emergency information in times of natural disasters and national crises and is under investigation for further end use application in government as well as military application fields.Communication via LTE has some vulnerabilities. This drawback is a matter of concern since it is possible to completely take down the LTE network or at least partially block communication, intentionally with the help of jamming signals, or unintentionally through various forms of interference.An example of unintentional interference issues is the frequently discussed co-existence issues with Air Traffic Control (ATC) S-band radar and Digital TV bands. The in-device co-existence challenge is also a potentially important issue with the rapid evolution of multi-standard radios.This White Paper will focus on the vulnerabilities of LTE communication by explaining LTE jamming and unintentional interference problems, address the coexistence issues with other services, and discuss the mitigation options to build a broad perspective on the possible deployment of the LTE technology for future military and civil governmental applications.Understanding the susceptance of new technologies to known and expected environments is critical to the adoption for defense applications

The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of commercial networks is strongly increasing around the globe. LTE has become the fastest developing mobile system technology. As other cellular technologies LTE is continuously worked on in terms of improvements. 3GPP groups added technology components into so called releases. Initial enhancements were included in 3GPP Release 9, followed by more significant improvements in 3GPP Release 10, also known as LTE-Advanced. Beyond Release 10 a number of different market terms have been used. However 3GPP reaffirmed that the naming for the technology family and its evolution continues to be covered by the term LTE-Advanced. I.e. LTE-Advanced remains the correct description for specifications defined from Release 10 onwards, including 3GPP Release 12. This white paper summarizes improvements specified in 3GPP Release 11.
