“Filter Design for Modern (Communication and Other) Systems-2021 Update!”

With usable RF spectrum as one of the most expensive-and usually unavailable-natural resources, frequency subdivision techniques are critically important for protection of both the content producer and the consumer.  The use of filters to provide walls to ensure isolation of users from one another is common, but the design of such filters is difficult because of user proximity, both spectral and physical.  With spectrum more costly than hardware, the ordered metrics for filters have been performance, size, reliability, and lastly, selling cost. However, the current proliferation of new wireless technology and IoT potentially impacts the importance of each metric.  As well, the migration of data transmission to ever-higher frequencies, i.e., up to and including the THz region, has a major impact on manufacturing technology.  In this paper we will discuss topology and manufacturing technology for the most recent approaches to implementation of such filters.

Millimeter-wave and sub-TeraHz technology and research trends on filters: An industry view”

High interest in millimeter-wave and sub-TeraHz bands has been rising in the recent years due to the enormous amount of under-utilized bandwidth that lies in this part of the electromagnetic spectrum. Technical advantages and large channel bandwidths make (sub)millimeter-wave suitable for the very high data rates required by enhanced Mobile BroadBand as well as for the new applications and services. In 5G mm-Wave front-ends, the use of filters is necessary to attenuate out-of-band signals such as a wideband noise, signal harmonics and unwanted harmonics: to suppress the unwanted interference signals, the antenna and the filter are usually designed individually and then cascaded by an extra transmission line. In addition to important technology directions like Substrate Integrated Waveguide (SIW) and the use of dual and multi-mode structures other important technical research trends are analyzed: mm-wave front-ends end-to-end cross layer design for architectures with an increasingly high level of integration and complexity and compact and low cost tunable structures.

“ Substrate Integrated Waveguide Multiband Bandpass Filters and Multiplexers”

Multiband bandpass filters (BPFs) and multiplexers are indispensable in emerging wireless communication and sensing systems characterized by various key performance indexes (KPIs) in connection with design metrics such as cost-effectiveness, performance reliability, dimensional compactness, integration density, and power handling capability. Generally, they are developed for either the realization of filtering and isolating functions in transceivers or the implementation of multi-function and multi-standard systems. As a well-established MHz-through-THz technology, the substrate integrated waveguide (SIW) has provided an attractive and effective solution for the development of cost-effective, self-packaged, and high-quality multiband BPFs and multiplexers benefitting from its inherent merits of low-cost, low-loss, high-density integration, and high-power handling capability. In this talk, technical approaches, design methodologies, implementation techniques, and practical demonstrations of SIW multiband BPFs and multiplexers are reviewed and discussed in terms of design features and application requirements, including a variety of state-of-the-art schemes of implementation including shunting, multimode resonator, multimode-shunting hybrid, and splitting types. Development roadmap and prospective applications are also briefly described.
