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.
Goals
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.
