Waveguide Filter Solutions up to 400 GHz
Waveguide filters engineered for frequencies up to 400 GHz provide critical signal conditioning capabilities for sub-THz communication and sensing systems. The product range encompasses bandpass, highpass, and lowpass filter configurations across WR-code waveguide standards, addressing emerging applications in E-Band, W-Band, D-Band, and beyond. These filters represent essential building blocks for advanced RF and millimeter-wave system architectures.
