As mobile wireless technology moves from LTE to 5G, a common question we hear is “How is filtering going to be handled in the unfamiliar territory of millimeter wavelengths?” There is a lot of uncertainty around what filters will be required, where they need to be placed in the base station, how good they need to be, and so forth.

With more than 40 years of experience working with millimeter wave (mmWave) applications, our engineers at Knowles Precision Devices understand the critical features needed to implement microwave filters for 5G technology and can help address these questions and concerns. Additionally, our filter technology addresses the challenge of implementing high-performance filters at mmWave frequencies.

At a high-level, our 26GHz, 28GHz, and 39GHz catalog filters provide the following features:

  1. 3 GHz of bandwidth
  2. Greater than 50 dB rejection
  3. Are 20x smaller than current alternatives while implemented in surface mount packages for standard tune-free assembly
  4. Have temperature stable operation from -55°C to +125°C

To help you navigate some of the issues and options when considering filtering for a 5G system and better understand how our filters can help, we put together the following collection of comprehensive resources for you to explore:
