With the surge in global usage of internet in smartphones, so has the need for extra Bandwidth requirements with simultaneous shared antenna capabilities for multi-channel video streaming and data speeds up surged. In order to meet design specifications two different ECADs namely ADS and AWR were used based on the High Frequency Engineering Design requirement and to obtain accurate RF results. A comprehensive design of RF Wilkinson Power Divider (WPD) incorporating microstrip lines in two-sectional configuration including EM model testing for device modeling, using RF test bench consisting of Fitted and Discrete frequency interpolation points have been carried out. Receiver (RX) System modeling results using 1-tone, 2-tone and 3-tone RF signals are meticulously presented along with analytical results for RX System analysis and synthesis. Exhaustive simulations have been carried out in all cases along with comparisons using ADS as the primary software tool. During these investigations the theoretical and simulation results are found to be in good agreement at System level, including design validation and modeling of the integrated RX module. The design of Bandpass Filters (BPF), Quadrature (90°) Hybrid Branch Line Coupler (BLC) incorporating microstrips and a 3 dB filter in four port network configuration has been carried out. It incorporates the EM model for device modeling, using Full-wave analysis consisting of Fitted and Discrete frequency interpolation points. Comprehensive RF Budget Power Analysis and Optimizations of Radio Link with the modeling results achieved by Small and Large Signal analysis are meticulously presented. During the investigations carried out using the ADS Harmonic Balance tool for Noise control, the hypothetical simulation results are found to be in good agreement at System level. These include design validation and modeling effects of the integrated RX System Front End module for 5G Communications. An introduction to establish a common level of knowledge and project advancement at System level platform is also addressed. Frequency response definitions of conventional BPF for 3rd order Chebyshev type – I filter approximations are discussed. In the end, the derivation of S-parameters matrix for the BLC carried out using the well-known Even-Odd mode network analysis is presented. During the 5G investigations, eight modules have been built mostly based on the Fundamentals of Physics, Semiconductors and Circuit Theory including the Patch Antennas, BPF, Couplers, Transmitter (TX), RX and Switches etc. The Switch between the Antenna and TX and/or RX must be equipped to handle high power when connected to the TX, and LO-Power when connected to the RX. In order to meet these requirements, the p-i-n diodes with forward and reverse biases have been used, respectively. Its Phase shifting capability is deployed while designing the Antenna. The Varactor diode is used in designing wideband BPF because the diode resonates at frequencies at the application of different reverse biased modes. All principles of Device Physics, Semiconductor Fundamentals and Circuit Theory are integrated in the Author’s MMIC Design and Fabrication Course.
