Abstract— This paper presents two W-band waveguide bandpass filters, one fabricated using laser micromachining and the other 3-D printing. Both filters are based on coupled resonators and are designed to have a Chebyshev response. The first filter is for laser micromachining and it is designed to have a compact structure allowing the whole filter to be made from a single metal workpiece. This eliminates the need to split the filter into several layers and therefore yields an enhanced performance in terms of low insertion loss and good durability.

Renens, Switzerland – August 29, 2019 – SWISSto12, a provider of telecommunications components for the satellite and aerospace industries, announced today the closing of a CHF 18.1M (USD 18.5M) Series B financing round led by Swisscanto Invest by Zürcher Kantonalbank and Swisscom Ventures and returning investor Constantia New Business (CNB).
This new round will accelerate the company’s industrialization and the commercial deployment of antenna products for communication satellites. The company will also direct the funding toward the introduction of new advanced communication payloads for the
