ANTENNA SHARING
LINX ANTENNA OPTIONS
LINX CONNECTOR OPTIONS
Many times when a transmitter
and
combined
transceiver the designer will
find it advantageous for the
modules to share a single
antenna. To accomplish this an
antenna switch must be used
to provide isolation between
each of the modules. There
are a wide variety of antenna
switches available which are
cost-effective and straight-
forward to use. Among the most
popular are switches from Alpha, Motorola, Philips, TriQuint, and NEC. Look for
an antenna switch that has high isolation and low loss at the desired frequency
of operation. Generally, the TX or RX status of a switch will be controlled by a
product’s microprocessor, but selection may also be made manually by the user.
In some cases where the characteristics of the TX and RX antennas need to be
different or switch losses are unacceptable the designer may find it more
practical to utilize two discrete antennas.
Linx offers a full line of antennas which
are optimized for the frequencies at
which
antennas are cost-effectively priced in
volume and designed to maximize the
performance of your product. For
complete details,visit the Linx website at
www.linxtechnologies.com, or contact
the Linx literature department at

The FCC requires that antennas designed for use on Part 15 products be either
permanently attached, or utilize a unique and proprietary connector not available
to the general public. Linx offers a full line of connectors designed to comply with
these requirements. To insure the continued compliance of these connectors,
details are not available on our website. However, complete connector
specifications may be obtained by contacting the Linx literature department at
