We introduce
a dual-band Lattice balun for multinuclear MRI
applications. This dual band balun is miniaturized and can be integrated
into a coil’s feed board and has high common-mode rejection ratio and low
insertion loss.

Diagram of a dual-band Lattice balun with 8 lumped elements, and relationships
between the values of each capacitor/inductor.
Fig. 4 (a)
Photograph of a constructed dual-band balun and its size comparison with a US
quarter. (b) Bench test setup and (c) bench test measurements of the magnitude
and phase difference between the two ports. The ideal magnitude/phase
difference should be 0 dB/180 degree at both frequencies.
