Design of a high-power and low-noise transmit-receive front-end module for WiFi6/6e

In this work is presented the design procedure and layout of a WiFi 6/6e front-end switch and low noise amplifier in a SiGe BiCMOS technology, aiming at performances comparable with the available commercial solutions. For the SPDT switch are used MOSFETs in triple n-well, while for the LNA’s active devices, are used HBTs. In chapter 1 are introduced the WiFi 6/6e standard and the SiGe BiCMOS technology, with the analysis of its devices. In chapter 2 the figures of merits and the basic topologies of SPDT switches are presented. In chapter 3, the proposed asymmetric SPDT switch structure is discussed. The design considerations for the switch realization and simulations are presented in chapter 4. In chapter 5 is presented a rigorous method analysis of stability of feedback amplifier. Then, the figures of merit of a low noise amplifier are discussed in chapter 6. The final low noise amplifier design procedure and realization are presented in chapters 7 and 4. In chapter 9 the proposed SPDT and LNA of this work are compared with others relevant works presented in the literature and other commercial solutions.
