New waveguide low-pass filters provide 100 dB rejection

20 February 2008 Telecoms, Datacoms, Wireless, IoT

The new AMQ-LP1 series of waveguide low-pass filters from Link Microtek have been designed to provide a rejection of better than 100 dB, falling to only 70 dB at band edges.

The new filter series comprises five standard parts, using waveguide sizes of WR340, WR137, WR112, WR90 and WR75 to deliver cut-off frequencies of 2,75, 8,15, 9,00, 10,40 and 13,50 GHz respectively.

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 0,6 dB, and a minimum return loss of typically 20 dB. Fabricated from solid aluminium using CNC machines, they 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 +50°C.

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.
