This work describes a geometrically decoupled three-element array triple-tuned for ¹H, ¹³C, and ³¹P at 3T implemented with switchable matching and tuning using PIN diodes. These particular nuclei were chosen to demonstrate the frequency range of the method, but the approach is extendable to any nuclei of interest. Although the Q of the coils was degraded by the switching network, the use of PIN diodes enabled straightforward tuning and development.
