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 operation 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.
K&L designs and manufactures a full line of RF and microwave filters, duplexers and subassemblies, including ceramic, lumped element, cavity, waveguide and tunable filters. K&L supplies many of today's most significant military and homeland security defense electronics programs. Applications include satellite communications, radar, radio communications, fire control radars, telemetry applications, missile guidance systems, mobile radio base stations and air traffic control and communications. Commercial products include high-performance receive and transmit filters, delay line filters, duplexers and diplexers, combiners, receive multi-couplers, wireless system assemblies for base station requirements and lower-cost ceramic and lumped element parts.
K&L's mission is to produce high-quality, cost-effective solutions based on customers' specific needs. By controlling internal design and production processes, K&L ensures and guarantees high quality and exceptional product performance. The K&L team is committed to achieving excellence through aggressive investment in research and development, through capital investments in manufacturing technology and through the use of proven and innovative designs.
K&L maintains a large staff of design and applications engineers with access to an extensive design library and a variety of software tools for approximation, synthesis, realization, analysis, and simulation. Two Applied R&D groups focus on developing advanced passive and active solutions for customer requirements. Specialized testing equipment, including high-power and high-frequency devices, assists with verification.
K&L has been a pioneer in vertical integration in the filter industry and continues to set the standard. Numerous CNC machining stations are networked with CAD/CAM computing stations, allowing efficient transfer of data from one process area to the next. A new state-of-the-art plating facility, temperature chambers, vibration and leak testing equipment, laser-welding and laser-labeling devices, and 150 network analyzers support efficient flow of product throughout the company to meet delivery deadlines. In addition to significant investment in production and testing equipment, K&L streamlines production by teaming with customers to implement lean manufacturing and maintains a Dominican Republic manufacturing facility for high-volume, commercial throughput.
Workmanship is a priority at K&L, and has been over the company's 40-year history. J-STD training and certification helps ensure quality in hands-on detail, and conformance to AS9100 policies and use of company-wide preventive and corrective action software contribute to overall continuous improvement. Customized automated testing software, rooted in twenty years of automated testing experience, is deployed throughout the company.
