Washability
The modules are wash resistant, but are not hermetically sealed. Linx
recommends wash-free manufacturing; however, the modules can be
subjected to a wash cycle provided that a drying time is allowed prior to
applying electrical power to the modules. The drying time should be
sufficient to allow any moisture that may have migrated into the module to
evaporate, thus eliminating the potential for shorting damage during
power-up or testing. If the wash contains contaminants, the performance
may be adversely affected, even after drying.
Antenna Considerations
The choice of antennas is a critical and
often overlooked design consideration.
The range, performance, and legality of
an RF link are critically dependent upon
the antenna. While adequate antenna
performance can often be obtained by
trial and error methods, antenna design
and matching is a complex task.
Figure 32: Linx Antennas
A professionally designed antenna such
as those from Linx will help ensure
maximum performance and FCC compliance.
Linx transmitters are capable of achieving output power in excess of some
legal limits. This allows the designer to use an inefficient antenna, such as a
loop trace or helical, to meet size, cost, or cosmetic requirements and still
achieve full legal output power for maximum range. If an efficient antenna is
used, then some attenuation of the output power will likely be needed. This
can easily be accomplished by using the LADJ line or a T-pad attenuator.
For more details on T-pad attenuator design, please see Application Note
AN-00150.
A receiver antenna should be optimized for the frequency or band in which
the receiver operates and to minimize the reception of off-frequency
signals. The efficiency of the receiver’s antenna is critical to maximizing
range performance. Unlike the transmitter antenna, where legal operation
may mandate attenuation or a reduction in antenna efficiency, the receiver’s
antenna should be optimized as much as is practical.
