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.

MIPS Project

Cross Coupled Filter Synthesis

Project #

1616

MIPS Round

16 |

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.

[Mtech] is invaluable to companies like ours in that it allows us to leverage our own resources with those of the university and the national laboratories to maximize the output of our research and development efforts. I feel that the activities to-date, along with those to follow through this program, in the future, will be instrumental in permitting K&L Microwave to maintain its position as the market leader in microwave filters and to continue to be an aggressive growth company.

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.

Dr. Zaki’s software is in use today in an expanded product line and a new filter design, based on the use of high-temperature superconducting materials.
