High-Performance Dielectric Resonator (DR) Filters Enhance Coexistence of Wi-Fi 6E/7 Frequency Bands

July 15, 2024

Johanson Technology introduces a new pair of high-performance dielectric resonator (DR) filters, P/N 5492BP49A0685001U and P/N 6525BP49A1200001U, designed to significantly enhance the coexistence of 5 GHz (UNII 1-3) and 6 GHz (UNII 5-8) WiFi bands. These filters provide superior performance in managing interference and optimizing signal integrity, ensuring seamless operation in advanced WiFi systems.

Both ceramic resonator filters exhibit high selectivity and low insertion loss to provide high attenuation of adjacent WiFi frequency bands with minimal signal loss within the passbands. This reduces interference and allows for cleaner signal transmission and reception while preserving signal strength and improving overall system performance. Operating within a wide temperature range of -40°C to +100°C, these filters are reliable in various environmental conditions.

Key Features and Benefits

  • Enhanced Coexistence: Designed to provide high attenuation of adjacent frequency bands, reducing interference and allowing for cleaner signal transmission and reception.
  • Low Insertion Loss: Ensures minimal signal loss within the passbands, preserving signal strength and improving overall system performance.
  • Compact SMD Design: Ideal for space-constrained applications, making them suitable for a wide range of consumer and industrial WiFi devices.
  • High Selectivity: Ensures that unwanted frequencies are effectively attenuated, crucial for maintaining signal integrity in complex RF environments.
  • Robust Performance: Reliable in various environmental conditions, operating within a wide temperature range of -40°C to +100°C.
