Suspended Substrate Stripline RF Filters

Suspended Substrate Stripline (SSS) is a printed circuit board topology that can be used for RF filter applications ranging in frequency from 500 MHz to 28 GHz.

This bandwidth is suitable for high and low pass filters that can be combined to form broadband filters and multiplexers. These designs result in highly selective band edges, low insertion loss and a broad range of impedance values.

In addition, the SSS technology provides very repeatable performance characteristics. This is mechanically achieved by compressing a double sided printed circuit board between two metallic planes with air cavities.

Due to the shielded structure, RF leakage is minimized, package size and cost is reduced. High power applications can be realized using machined conductive metal and either air or Teflon material in place of the printed circuit board copper and substrate.

America's Oldest. A History of Innovation.

Over the past 70 years, the electronics manufacturing industry has changed dramatically as the industry continues to adapt to evolving demands and technology. Epec is at the forefront of innovation, with the expertise and agility to move at the speed of today’s businesses. At Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us or creating a new product introduction (NPI) process that helps our customers get to market faster, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 70 years and then some.
