New applications, that are bandwidth starving, keep moving the civilian-oriented commercial products well into the microwave and even the millimeter (mm)-wave bands.įilters in the front-end module play a significant role for controlling the frequency bands of wireless standards as well as block the unwanted frequency bands. The need for mobile communication systems for voice, video, and data has created a very congested spectrum in the UHF, L and S bands. To meet expectations and deliver the required bandwidth, new components, circuits, systems, and frequency spectra must be constantly made available for mixed signal applications. Budding trends of dependence on wireless connectivity and increasing expectations of the information expressway are the strong indicators show that wireless technologies will continue to grow.

Embedded layers are integrated for 3D integration, parasitics are removed and interconnection losses are bargained by de embedding method. High Q passives such as inductors, capacitors and matching networks are embedded in the filter. A low profile, compact filter with high performance and high rejection out of band is presented.
