Knowles Precision Devices Filter Products For 5G mmWave

Filter Technology for the n257 and n621 bands

28GHz Filter Products

Knowles Precision Devices (DLI) Filter Technology addresses the challenge of implementing high performance filters at mmWave frequencies. Our catalog filters provide up to 3GHz of bandwidth, > 50dB rejection, are 20x smaller than current alternatives while implemented in surface mount packages for standard tune-free assembly and provide temperature stable operation from -55°C to +125°C.
