Non-Volatile CBRAM/MIM Switching Technology for Electronically Reconfigurable Passive Microwave Devices

4Fully Passive Solid-State Electronically Reconfigurable Filter and Antenna Models

4.1. Introduction

In this chapter, we present the applications of the proposed conductive bridging random access memory/metal insulator metal (CBRAM/MIM) radio frequency (RF) switches for electronically reconfigurable filters and antennas. We try to demonstrate the potential applications of CBRAM/MIM switches for enhancing the performance of classic RF and microwave devices. In order to highlight the advantages of integrating CBRAM/MIM switches into passive RF and microwave devices, we examine the generalized design topology of a band-stop filter and a parasitic element (PE)-loaded dipole antenna. We strongly believe that the reader will be convinced, by the end of this chapter, of the conclusive advantages of non-volatile reconfigurable RF devices based on the proposed switch technology, in contrast to their vintage predecessors, for low-power standalone applications.

4.2. CBRAM-MIM switches for electronically reconfigurable filter applications

Multiband reconfigurable filters would enormously benefit the microwave and wireless communication of the present era (Hong 2009; Al-Yasir et al. 2019). Electronically reconfigurable multiband RF filters would support reductions in the physical volume and signal processing budget of a system, contributing to increased versatility. Ample research has been carried out in this domain and is still advancing at a good rate, and a handful of remarkable prototypes ...
