ABSTRACT:
A tuner module comprising a tuner and a tuner enclosure. The tuner includes a substrate containing filter coils and the tuner enclosure includes at least one partition plate placed between filter coils of the tuner to improve the isolation between the filter coils. The substrate may also contain plated through holes placed beneath a partition plate which further improves isolation between the filter coils. In some embodiments, the substrate is comprised of a coil layer having a planar coil, a shield layer, and a dielectric layer. The dielectric layer is placed between the coil and shield layers and provides a distance between the two layers to achieve a particular quality factor level of the planar coil. In some embodiments, the tuner enclosure further includes a shielding case that extends to the base of the substrate, is comprised of a metal material, and is mechanically connected with the substrate.
