L Band Triplexer Study The
object of the study was to determine if putting three very close RF signals
together would force unreasonable circuit design complexity on commercial GPS
receiver manufacturers. The
study consisted of reviewing low loss techniques capable of de-multiplexing
the three L band signals being supplied from a single antenna element in an
environment where large interference signals were present. Other
technical issues included bandwidth specification limitations, antenna
element feed options and group delay distortion on the individual
signals. The study concluded the frequency choices were reasonable and practical. |
