Suspended Stripline Filter
The next two 5G bands for the United States market are 27.5-28.35GHz and 37-40GHz. At these higher frequencies CMI designs filters with either waveguide, microstrip, stripline, slabline or suspended strip line. At CMI we developed a surface mount 28GHz suspended strip line filter tailored to the RF properties of the customers circuit board assembly. The customer’s application was wideband communications to a drone so weight was an important factor in the design. Below is the picture of the suspended strip line filter.
