Abstract

This letter presents a 8th-order dual-mode waveguide filter, fabricated using selective laser melting (SLM) technique. The filter employs four dimpled ellipsoid dual-mode resonators, operating at the fundamental TM101 mode. During printing, the filter can be mechanically self-supported without any internal supports. Compared to the filters employing tuning posts, the proposed filter is less sensitive to fabrication errors in terms of their impacts on passband return loss (RL), frequency shift and bandwidth. The filter was demonstrated at WR-112 band (7-10 GHz), with a measured insertion loss of 0.25-0.4 dB and a RL >15 dB across the passband of 8-8.46 GHz.
