Abstract

Several aspects of mixer designs have been discussed in this chapter. Several mixer specifications were considered. In addition, several examples were considered for the illustration. With detailed analysis of works from several research groups, diodemixers as well as several features of transistor mixers, including their various forms, were discussed in detail. Mixers are an essential component of 5G communication architecture. Their incorporation into 5G communication architecture and subsequent implementation alongside other components will be critical for the future of 5G.

6.1 Introduction

In recent years, Millimeter wave (mmW) communication in the 28 GHz radio frequency band has grown in importance for 5G (fifth generation) wireless communication and radar applications [1]. In the current technologies, the problem of high data rate, wider bandwidth, and low latency is prevailing. These issues are not addressed by fourth generation (4G) communication via LTE (Long Term Evolution). Therefore, more advanced communication techniques such as 5G is needed which can resolved ...
