Micro Communications, Inc. offers a full
range of UHF channel combiners in
starpoint or (manifold) configurations. The
channels are combined into one antenna
feed line.
The number of cavities in any of these
combiners is determined by the spacing
between the channels within the system.
Typically, for most requirements, four
bandpass cavities per channel will suffice
with a channel spacing of 24 MHz or more.
The cavities are designed and constructed
to ensure good stability over a wide range
of environmental changes.
A variety of layouts are available with overall
sizes depending on power levels, number of
channels to be combined and other considerations. Construction is usually from rugged
aluminum welded flanged cavities within a
freestanding aluminum frame. MCI bandpass
filters, as always, are precision tuned at the
factory to provide optimal reflective and transmissive phase matching, ensuring good inband VSWR while minimizing insertion
losses. In systems where the channel spacings are less than 24MHz, the use of six
section bandpass filters are incorporated.
Thermally stable filter designs are also available.
