SMC Offers a full range of rectangular waveguide Lowpass Harmonic Filters covering the waveguide sizes WR19 thru WR650. Their superior electrical performance are characterized by low loss, wide-out-of-band rejection, in and out of band spurious free response and very high power handling capability due to our proprietary design techniques developed by SMC.
