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.
