Company Profile
Epsilon Lambda Electronics has been working in the
millimeter and microwave industry for over 27 years. Since 1974, we have been
performing engineering R & D as well as production manufacturing of
components and integrated subsystems from 10 to 94 GHz. In our years of
business, we have become the foremost innovators of Integrated Millimeter Wave
Subsystems. Today, Epsilon Lambda leads the way in the development and
manufacture of low cost, integrated subsystems for the emerging automotive
collision warning/intelligent cruise control radar systems market. Epsilon
Lambda was the world's first commercial manufacturer of collision warning
subsystems when the entire fleet of 1,700 Greyhound buses
were equipped with our hardware in 1992. Prototype and production orders
for CW/ICC antenna/transceivers at 24 GHz, 60 GHz, and 77 GHz have been
received from customers in the USA, Japan, and Europe.
Epsilon Lambda's expertise extends to other Millimeter
wave radar subsystems. Our ability to take a customer's radar requirements and
custom design a low cost subsystem that can be manufactured in quantity is
exceptional. Whether the application is communications, intelligent
transportation, or military, our design engineers are ready to discuss your
application needs.
Epsilon Lambda is a leader in the development and
production of microstrip patch array antennas.
Production quantities at 24 GHz and 35 GHz have been delivered. Designs are
available to 100 GHz which include fixed beam, linear polarization, circular
polarization, and monopulse. A fixed, phase scanned
patch array antenna was demonstrated in 2000.
Epsilon Lambda is also able to provide high quality Gunn
oscillators as well as a strong selection of waveguide components. The
following pages provide an overview of our capabilities ranging from radar

Collision Warning / Intelligent Cruise Control Subsystems
Epsilon Lambda has developed and manufactured millimeter radar
antenna-transceiver subsystems during the past ten years for application to
forward looking collision warning/intelligent cruise control. Low cost,
integrated designs at 24, 60, and 77 GHz have been developed and produced at
quantities of hundreds to thousands.
Epsilon Lambda is a leader in
developing and manufacturing integrated subsystems for CW/ICC radar. The first
to manufacture such products, the entire fleet of Greyhound buses was equipped
with 24 GHz antenna/transceiver subsystems developed and manufactured by
Epsilon Lambda. Recent developments include low cost, miniaturized antenna/transceivers
for the 60 and 77 GHz bands. Technology innovation will continue in this
product, both in design and manufacturing. Epsilon Lambda continues to be a
technology innovator and will pioneer the production effort which meets the
demand for very low cost subsystem assemblies.

Now Available- Wide Field-of-View, High-Performance, Mechanically Scanned Transceiver Antenna Subsystems.
The Automotive industry, which is now introducing first model ACC products, is necessarily
moving towards solving the more complex issues associated with FLR radar. Those
issues include: slow speed stop/go operation, detecting short range cut in
vehicles, recognizing stopped objects for reliable path prediction, and
collision warning.
An essential requirement to
solve any of these issues is to increase the azimuth field-of-view (FOV) of the
antenna. Typical ACC of first generation design have FOV of +/-6 degrees in
azimuth. This FOV must increase to +/-10 degrees or more. For very wide
Field-of-View applications, angles of 45 degrees are readily achieved (the
angle may be specified at time of order). Most of the first generation products
cannot achieve this without loss of performance (gain, angle resolution,
detection range etc.), increased package size, increase in cost or all of these
design compromises. The design approach of Epsilon Lambda however allows
implementation of wide FOV with no compromise in any of these design features.
The antenna/transceiver is a single assembly that is pivoted to achieve azimuth
scanning. For the first time, developers of FLR radar systems have the choice
of a compact, high performance, wide FOV, low cost antenna/transceiver.

Local Multipoint Distribution Service
LMDS, LMCS Communications
The Canadian Government,
during 1996, awarded licenses for 28 GHz LMCS communication services. In the
spring of 1998, the United States Federal Communications Commission conducted
auctions of millimeter wave (frequency 27.5-31.3 GHz) bands for use in LMDS
Communications.
Holding a license is only one
element of success in this embryonic market opportunity. The primary key is
offering reliable, low cost equipment at the Consumer (CPE) site. Epsilon
Lambda Electronics is prepared to partner with major telecommunications
corporations / license holders in North America and other world markets to make
available consumer equipment of unique and advantageous design. Custom features
with low cost manufacturing are the hallmark of Epsilon Lambda's millimeter
subsystems. License holders can tap into the finest design, development, and
manufacturing capability available to achieve a competitive advantage in
performance, features, and quality.

Gunn Diode
Oscillators
- ELF, ELM, and ELE Series
Epsilon Lambda Gunn Oscillators are available in Fixed Frequency (ELF series),
Mechanically Tuned (ELM), and Electronically Tuned (ELE) versions. They combine
proprietary circuit design capability and experience with the highly reliable
Gunn diode for the generation of RF power in the microwave and millimeter wave
frequency ranges.
- Specially designed for low
AM and FM noise characteristics, these oscillators are ideally suited for
many bench test source applications.
- DC power is applied to the
Gunn oscillators through a low pass EMI filter. The oscillators have a
built-in bias suppression circuit to eliminate bias circuit oscillations.
- Frequency tuning of
mechanically tuned oscillators is accomplished with a micrometer drive
mechanism, which enables convenient,smooth
tuning as well as reliable frequency setting.
- Frequency tuning of
electronically tuned oscillators is accomplished with the addition of a varactor diode and a female SMA connector for the varactor tuning port.
- Electrical performance
specified at 25 degree C room temperature.
- The typical operation temperature
of the oscillator is -20 deg.C to +50 deg.C. Wider
temperature range oscillators or temperature compensated oscillators are
available as a special item. Oscillators with heaters are stabilized at a
case temperature of 55 deg. C typical.
