3-D Printed W-band Waveguide Iris Bandpass Filter With High Production Accuracy Using SLS Technology and Plastic Plating Technology

Abstract

We developed a simple and cost-effective solution for millimeter-wave waveguide component production, using additive manufacturing (3-D printing) with plastic plating technology in W-band. The 3-D printing is based on a selective laser sintering technology.

In this paper, we demonstrate operation of a 105-GHz-band WR-10 BPF. The BPF is based on a fourth-order Chebyshev BPF with a bandwidth of 9.04 GHz, and an insertion loss of 0.66 dB at the center frequency of 103.3 GHz.
