Company History


EMR Corporation was founded in 1980 by William Lieske, Sr. as an OEM supplier of ferrite and hybrid devices to the land mobile communications and broadcast industries. Bill has been involved in radio communications for more than 60 years. Beginning with a radio amateur license at the age of 13, he went on to work in military radar, public safety, radio communication manufacturing and commercial corporate sales. As the chief engineer, Bill's approach to R.F. systems component design is without parallel in the industry. Bill's work has helped set standards in the U.S. and international land mobile communications and antenna site management industries.

Soon after founding EMR Bill expanded his scope of activities to include the design and manufacturing of cavity resonant devices and complex combination of R.F. filtering products, such as antenna duplexers, hybrid and cavity resonant combining networks and receiver multicoupling.

In early 1992, EMR began manufacturing amplifiers for land mobile and broadcast receiver applications. EMR's product line includes a line of receiver pre-amplifiers, hybrid dividers and amplifiers in various bands for up to 250 watts output power. We also offer a complete line of antenna site and mobile application filtering products covering the R.F. spectrum from 30 MHz to 2.8 GHz.

EMR has built an efficient and effective team of highly trained, motivated, dedicated employees. With our specialized team members providing leadership, top notch engineering and state of the art manufacturing we design and manufacture a wide variety of custom products as well as products for standardized applications. EMR excels in unique designs to meet exact customer requirements.

EMR Corporation provides design, supply and implementation of complete R.F. communication systems. Our corporate philosophy is:

TO PROVIDE HIGH QUALITY PRODUCTS, TECHNICAL
