Filters up to 400 GHz

Waveguide Filters up to 400 GHz – Precise Frequency Selectivity for Demanding High-Frequency Applications

Waveguide filters from bq-microwave provide selective frequency processing across the entire RF, microwave, and mmWave spectrum up to 400 GHz. Our comprehensive product range includes bandpass, highpass, lowpass, and bandstop filters in various waveguide configurations (WR19 to WR2.8), optimized for minimal insertion loss and maximum signal integrity.

Key Features

• Frequency range up to 400 GHz (bandpass filters WR19–WR2.8)
• Multiple filter types: bandpass, highpass (up to 330 GHz), lowpass (up to 140 GHz), bandstop (up to 140 GHz)
• Precise passband characteristics with steep rejection slopes
• Low VSWR values and reduced phase dispersion
• Robust waveguide construction for mechanical stability
• Custom designs available to specification

Applications

• SATCOM and aerospace communications
• 5G/6G network infrastructure and test equipment
• Defense and military systems (Mil-Spec available)
• Automotive ADAS and radar systems
• Scientific and laboratory test and measurement
• High-frequency HPA and LNA integration systems

Technical Depth and Customer Flexibility

Waveguide technology offers distinct advantages over coaxial solutions at extreme high frequencies: lower dielectric losses, higher power handling, and optimal phase linearity. Our filters cover both standard bandwidths and narrowband requirements, ideal for FMCW radar, CW and pulsed systems, as well as frequency multiplexing architectures.

In addition to our standard off-the-shelf products, we develop custom filters for specific impedance requirements, flange configurations, and attenuation specifications. bq-microwave offers reliable availability, extensive stock levels, and technical expertise for complex RF integration projects.
