Waveguide low-pass filters provide 100dB rejection

The new devices are ideal for use as transmit reject filters and are precision engineered to achieve a Chebyshev ripple response with sharp cut-off, a maximum insertion loss of just 0.6dB, and a minimum return loss of typically 20dB.

Fabricated from solid aluminium using CNC machines, these reflective filters feature a corrugated internal design and are supplied with a satin black painted finish as standard. They have an operating temperature range of -30 to +50degC.

In addition to this standard range of low-pass filters, Link Microtek’s Engineering Division offers a rapid-turnaround custom design service for these filters for requirements such as non-standard waveguide sizes, flanges or cut-off frequencies.
