Merrimac Granted Multi-Mix(R) Mixer Patent

Apr 03, 2001, 01:00 ET from Merrimac Industries, Inc.

    WEST CALDWELL, N.J., April 3 /PRNewswire/ -- Merrimac Industries, Inc.
 (Amex:   MRM), a leader in the design and manufacture of RF Microwave
 components, assemblies and Micro-Multifunction (MMFM(R)) Modules, today
 announced that it has been granted a patent from the United States Patent &
 Trademark Office entitled "Microwave Mixer With Baluns Having Rectangular
 Coaxial Transmission Lines."
     The patent relates to an improved multilayer mixer that enables Merrimac
 to offer performance benefits over other currently available mixers for
 microwave integrated circuits (MIC) and monolithic microwave integrated
 circuits (MMIC) at reduced size, weight and cost.
     According to Chairman & CEO Mason N. Carter, the new technology broadens
 the universe of customers by increasing manufacturing flexibility and
 improving performance characteristics.  "This patent is another important step
 in positioning Merrimac as a leading producer of components and multifunction
 modules found in cutting-edge wireless, satellite and military communication
 systems.  We continue to meet the demands of both our existing customers and
 new customers who look to us to provide innovative solutions, in this case the
 improved design of mixers that are used to multiply and translate frequency.
     "Mixers are an important element in the design of wireless front-end
 transceivers, which are typically found in such applications as mobile radios,
 pagers, point-to-point and point-to-multipoint radios, local multipoint
 distribution services (LMDS), global positioning systems (GPS) and microwave
 TV/wireless cable signaling channeling line-of-sight communications systems
 from supplier transmitter to subscriber rooftop and set-top box.  Mixers
 integrated with a variety of Merrimac's Multi-Mix(R) filters form the basic
 building blocks for front-end transceiver designs."
     Present technologies have several shortcomings that the patent seeks to
 overcome.  The bandwidth provided by monolithic microwave integrated circuit
 (MMIC) technology is typically limited, and the development cost is high.
 Lumped-element technology has an upper frequency limitation, and is
 labor-intensive to produce.  Microwave integrated circuit (MIC) technology
 produces structures that are physically larger, and utilizes metal frames or
 housings that further increase the size of the package.
 
     About Merrimac
     Merrimac Industries, Inc. is a leader in the design and manufacture of RF
 Microwave components, assemblies and Micro-Multifunction (MMFM(R)) Modules
 serving the wireless telecommunications industry worldwide with enabling
 technologies for commercial applications.  Merrimac is focused on providing
 Total Integrated Packaging Solutions(TM) with Multi-Mix(R) Microtechnology, a
 leading edge competency providing value to our customers through
 miniaturization and integration.  The Multi-Mix(R) process for microwave,
 multilayer integrated MMFM(R) circuits is a patented method developed at
 Merrimac Industries based on fluoropolymer composite substrates.  The fusion
 bonding of multilayer structures provides a homogeneous dielectric medium for
 superior electrical performance at microwave frequencies.  The bonded layers
 may incorporate embedded semiconductor devices, MMICs, etched resistors,
 passive circuit elements and plated-through via holes to form a three-
 dimensional subsystem enclosure that requires no further packaging.  Merrimac
 Industries, Inc. is ISO 9001 certified.
     Merrimac Industries, Inc. and its subsidiary Filtran Microcircuits Inc.,
 with locations in West Caldwell, NJ, San Jose, Costa Rica and Ottawa, Ontario,
 Canada, have approximately 250 co-workers dedicated to the design and
 manufacture of signal processing components, gold plating of high frequency
 microstrip, bonded stripline and thick metal-backed Teflon (PTFE)
 micro-circuitry and subsystems providing Total Integrated Packaging
 Solutions(TM) wireless applications.  Merrimac (MRM) is listed on the American
 Stock Exchange.  For more information about Merrimac Industries, visit its

 pressures; the risk that the Company will not be able to continue to raise
 sufficient capital to expand its operations as currently contemplated by its
 business strategy; risks relating to governmental regulatory actions in
 communications and defense programs; risks associated with demand for and
 market acceptance of existing and newly developed products; and inventory
 risks due to technological innovation and product obsolescence, as well as
 other risks and uncertainties, including but not limited to those detailed
 from time to time in the Company's Securities and Exchange Commission filings.
