Filtering Components For 5G Networks

As 5G testing continues to grow and demand more requirements for filtering components. Corry Micronics (CMI) has developed all types of filtering using different technologies, and several that have been allocated for 5G. At lower frequencies in the US market centered around 600 MHz, filtering can be easily, and cost competitively designed using several different filtering technologies. Types of filters range from LC to cavity, combline, interdigital, Helical, ceramic resonator, and tubular.

An example of a standard LC discrete component filter is pictured below:

The next US 5G band has been allocated from 3100 MHz to 3550 MHz and at these frequencies, many filtering types work well including waveguide filtering. Below is an example of a cavity filter at these frequencies:

The next two 5G bands in the US market are 27.5 to 28.35 GHz and 37 to 40 GHz. CMI designs filters at these higher frequencies with waveguide, microstrip, stripline, stabline or suspended strip line. CMI has developed a surface mount 28 GHz suspended strip line filter tailored to the RF properties of a circuit board assembly for drone wideband communications. Below is the image and download of the suspended strip filter:

The highest band for 5G technologies in the US market is from 64 to 71 GHz, where research is still being done on what applications can be used for this range. Whatever the application CMI will have the filters needed to guard against interfering frequencies. This type filter is imaged below with its download:
