Product Lineup

For over 60 years TTE has been designing and manufacturing high performance RF and microwave filters. Custom orders are typical – not the exception – at TTE Filters. With decades of expertise, TTE is well-versed in filter technology, filter designs and filter applications.

This site hosts our extensive product database from our Filters companies: TTE Filters, Microwave Circuits (MWC) & Instec Filters. Use the tables founds on each product category page to search existing designs for an exact match, or a product and design that very closely matches your specifications and determine if it can be “tweaked” to match your exact requirements. In many cases, an already designed RF filter or a design from our engineering database may already exist and might only require some frequency shifting, or slight modification to the bandwidth, connector change or other parameters which will not require a total re-design.

Most of TTE’s products are custom-made and built to order. TTE maintains a large inventory of standard materials to enable delivery of most products within 2 weeks. Expedited lead times, as short as 3-5 days, are available on certain products. All TTE products are made in the USA and include a limited warranty. TTE offers all of its passive filters in the smallest practical sizes available.
