Micro Strip Line Design

It is advantageous to use the Micro Strip Line in high-
frequency transmission circuits because a low-loss trans-
mission can be achieved with this method. By etching the

dielectric base which has copper foil attached to both sides,
the Micro Strip Line will have a concentrated electric field

between the lines and ground, as shown in the following
diagram.

Lines with impedance Z

Ground pattern

Dielectric base

(dielectric constant:

)

The characteristic impedance of the lines Z

is determined

by the kind of base (dielectric constant), the base's thickness,
and the width of the lines, as expressed in the following

equation.

377

1+In W

W: Line width

: Effective dielectric constant

H: Dielectric base thickness

The copper foil thickness must be less than H.

The following graph shows this relationship.

(

)

For example, when creating 50- lines using a glass epoxy

base with a thickness of 1.6 mm, the above graph will yield a
w/h ratio of 1.7 for a dielectric constant of 4.8. Since the base
thickness is 1.6 mm, the width will be h × 1.7 2.7 mm.

The thickness of the copper foil "t" is ignored in this design
method, but it must be considered because large errors will

occur in extreme cases such as a foil thickness of t w.

In addition, with the Micro Strip Line design, the lines are too

short for the G6Y's intended frequency bandwidths, so we
can ignore conductive losses and the line's attenuation

constant.

The spacing of the Strip Lines and ground pattern should be
comparable to the width of the Strip Lines.

565

High Frequency Relay

G6Y

Design the pattern with the shortest possible distances.

Excessive distances will adversely effect the high-frequency

characteristics.

Spread the ground patterns as widely as possible so that

potential differences are unlikely to develop between the

ground patterns.

To avoid potential short-circuits, do not place the pattern's

leads near the point where the bottom of the Relay attaches

to the board.

Bending the Micro Strip Line

Elbow

Clip the corners

45°C

When the lines must curve, an elbow can be used as shown in

the diagram. A distance (D) between the lines of approximately

twice the line width is sufficient.

EXAMPLES OF MOUNTING DESIGNS

Since this example emphasizes reducing mounting costs,

expensive mounting methods, such as through-hole boards, are

not shown. If such methods are to be used, the characteristics

must be studied carefully, using the actual board configuration.

Using a Double-sided Paper Epoxy Board

When double-sided paper epoxy boards are used, the dielectric

constant will be approximately the same as that of glass epoxy

boards (

=4.8).

The width of the Strip Lines for a board with t=1.6 mm is 2.7 mm

for 50 and 1.8 mm for 75 . For a board with t=1.0 mm the

width is 1.7 mm for 50 and 0.8 mm for 75 .

The following diagram shows an example pattern, and the Micro

Strip Lines connected to the contact terminals are formed with

pattern widths derived from the description above. The width

between the Micro Strip Lines and ground patterns are

comparable to the Micro Strip Line width.

There are jumpers between the upper and lower patterns at the

points marked with Xs in the diagram. Improved characteristics

can be obtained with more jumper locations. This method yields

isolation characteristics of 65 dB to 75 dB at 500 MHz and 50 dB

at 900 MHz.

At this point in the diagram the component side is the entire

ground pattern side; but, you must set aside approximately

2.0 mm × 2.0 mm of the pattern for the contact terminals and

coil terminals.

Using a Single-sided Board

When a single-sided board is used, isolation characteristics of

only 60 dB to 70 dB at 200 MHz can be obtained. When high

frequency bands are to be used with a single-sided board, a

metal plate can be placed between the base and Relay and

connected to the ground pattern.

Pattern

G6Y

With this method a metal plate is placed between the Relay and

base and connected to the pattern, as shown in the above

diagram. The important point here is that 3 locations (the G6Y's

ground terminal, the metal plate's bent tabs (A), and the ground

pattern) are soldered together at the same time. This method

combines an inexpensive single-sided board and inexpensive

metal plate to yield the same characteristics as a double-sided

board. Good characteristics are obtained by grounding the G6Y's

ground terminal and metal plate in the same place.

The metal plate must be attached to the base as described here.

From this point, the methods used for Strip Line design are the

same as for the double-sided board.

1. Suitability for Use. Seller shall not be responsible for conformity with any stan-

dards, codes or regulations which apply to the combination of the Product in
Buyer's application or use of the Product. At Buyer's request, Seller will pro-
vide applicable third party certification documents identifying ratings and limita-
tions of use which apply to the Product. This information by itself is not
sufficient for a complete determination of the suitability of the Product in combi-
nation with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the partic-
ular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a non-
exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical

interference, or conditions or uses not described in this document.

(ii) Energy control systems, combustion systems, railroad systems, aviation

systems, medical equipment, amusement machines, vehicles, safety
equipment, and installations subject to
separate industry or government regulations.

(iii)Use in consumer products or any use in significant quantities.
(iv)Systems, machines and equipment that could present a risk to life or

property. Please know and observe all prohibitions of use applicable to this
product.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM
AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT
THE OMRON PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE
INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.

2. Programmable Products. Seller shall not be responsible for the user's

programming of a programmable product, or any consequence thereof.

3. Performance Data. Performance data given in this publication is provided as a

guide for the user in determining suitability and does not constitute a warranty.
It may represent the result of Seller's test conditions, and the users must corre-
late it to actual application requirements. Actual performance is subject to
Seller's Warranty and Limitations of Liability.

4. Change in Specifications. Product specifications and accessories may be

changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for your
application. Please consult with your Seller representative at any time to con-
firm actual specifications of purchased Product.

5. Errors and Omissions. The information in this publication has been carefully

checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors, or omissions.

6. RoHS Compliance. Where indicated, our products currently comply, to the best

of our knowledge as of the date of this publication, with the requirements of the
European Union's Directive on the Restriction of certain Hazardous Sub-
stances ("RoHS"), although the requirements of RoHS do not take effect until
