Waveguide LP filters offer 100-dB rejection

The AMQ-LP1 series waveguide low-pass filters provide a rejection of better than 100 dB—falling to only 70 dB at band edges. The series comprises five standard parts—using waveguide sizes of WR340, WR137, WR112, WR90 and WR75—to deliver cutoff frequencies of 2.75, 8.15, 9.00, 10.40, and 13.50 GHz, respectively.

The devices are suitable for use as transmit-reject filters and are precision engineered to achieve a Chebyshev ripple response with sharp cut-off. Maximum insertion loss is 0.6 dB, and minimum return loss is typically 20 dB. Operating temperature range is –30° to 50°C. (Contact Sales for pricing—available now.)
