5G feature-rich devices and applications demand the introduction of new and higher frequencies with increased capacity. The RF cavity filter is often the largest single component in a radio and its size drives costs in other areas. Macro cells and small cells will have more channels to increase capacity requiring MIMO (Multiple In Multiple Out) filters. These high-performance filters must be Isolated from one another.

The demands of each radio platform create unique challenges that require customized RF filter solutions. Our RF filter design experts have experience in custom solutions for many years up to 80Ghz. DAS, small cell, macro cell, MIMO and Radio Link experiences give us confidence in finding an optimal solution. We use established in-house tools, procedures, and supply chain to meet reliable results.

As 5G applications are used more widely in conjunction with radar and satellite, the signal landscape will get more complex. For example, Interference in CBRS can potentially interfere with highly sensitive Aviation (altimeter) equipment. Planning and discussion between industry associations must be held in advance of implementation.

Higher demands for performance, reducing power where possible and avoiding mixing of signals and added noise are important goals. This must be done using the least expensive approaches from design to Die Casting and secondary CNC Milling, plating and then assembly and test. Molex provides cavity filters with low Insertion Loss, high Rejection, and ultra-low PIM. Many MIMO filters require high Isolation between channels.
