Studying Bandwidths of Balancing Preamplifier Decoupling Networks

Year: 2024

Type: conference-paper

Abstract: Motivation: Lattice baluns are traditionally used in receive arrays to achieve common mode rejection and preamplifier decoupling. They, however, are limited to real impedance transformations only. Goal(s): New matching networks are sought that achieve noise matching and preamplifier decoupling, as well as common-mode rejection. Approach: In this abstract, new network topologies are introduced and their bandwidths are studied. Results: In addition to being more compact, the new networks offer a wider bandwidth as well as higher common-mode rejection. Thus, it is expected that the new networks are more resilient to component tolerances and loading effects, and they may enable multinuclear imaging. Impact: New topologies of preamplifier decoupling networks with integrated balun functionality are introduced. They offer wider bandwidth and higher common-mode rejection compared to traditional networks.
