ABSTRACT:
A central interconnector unit provides for the possible transfer therethrough of RF signals passing in m signal paths from respective signal sources to respective antennas disposed at a cellular telephony cell site to radiate those signals into different angular sectors of the site. The unit has a total capacity for amplifying such signals which is provided by n similar circuit pack amplifying sections (n being greater than m), having respective inputs and outputs connected to corresponding jack terminals on a backplane in the unit. Associated with the unit are a pool of p signal divider-combiner modules (p being greater than m) which each include (a) source and load terminals for exteriorly connecting the module to one of such sources and antennas, (b) a row of pairs of input and output section terminals pluggable into said jack terminals to connect the module to one or more of said sections and (c) divider and combiner units respectively connecting the source and load terminals of the module to, respectively, all input section terminals thereof and all output section terminals thereof. Different of the modules in the pool have different numbers of pairs of input and output section terminals. Different combination of m modules are withdrawable from the pool and insertable into the interconnector unit to allocate different fractions of said total amplifying capacity among different of said m signal paths.
