Company Description:
K&L Microwave is a subsidiary of Dover Corporation, a $7.5 billion Fortune 400 company traded on the New York Stock Exchange, recognized by top-tier defense contractors and wireless infrastructure providers as a world leader in the design and manufacture of RF and microwave filters, duplexers and integrated assemblies. K&L is AS9100 and ISO 14001 certified and offers customers the most extensive range of filter-based products in the industry, spanning from 0.3MHz to 94GHz.
K&L began operations over 40 years ago in a 1,400 square foot facility manufacturing custom filters primarily for the military sector. Today, with manufacturing facilities in the United States and the Dominican Republic and a global sales presence, K&L is the industry’s premier filter supplier for both military and commercial markets. Over 410 employees represent the engineering, sales and marketing, manufacturing and support personnel that enable K&L to support such a broad product and customer base.

Starting Date:
Aug 1995
MIPS Project Challenge:
K&L sought to increase the efficiency of its existing technology for cross-coupling filters.
Project Scope:
The goal of the project was to develop models and programs for determining the physical dimensions of the coupled filter structures. Using a full-wave approach, the team combined contour mode matching and orthogonal expansion to obtain the generalized scattering matrix of a cylindrical metal post in a rectangular waveguide. A cascading procedure using an S-matrix was employed with proper terminating conditions to compute natural resonant frequencies of the coupled resonators. The resulting program obtained excellent filter responses.

Results:
This project enabled K&L to grow its business by seven percent. The several projects that K&L did with MIPS’ support led to the addition of 91 jobs and $3 million in annual revenues. K&L credits the project in its move to broaden from defense into commercial markets.
The project resulted in two published papers and two doctoral theses.
