Re-configurable multiplexer, method for making it and branching unit for terrestrial radio links
First Claim
1. Reconfigurable multiplexer for wireless transceivers comprising a manifold (MF) and filter means to be connected to the manifold (MF) at proper locations (P1, P2, . . . P5), characterized in that at least one of said filter means comprises a filter head (FHD1, FHD2, . . . FHD5) connectable either to a corresponding covering plate (SC1, SC2, . . . SC5) for short circuit purposes or to a filter tail (FTL1, FTL2, . . . FTL5) in order to provide full filter functionality.

Abstract
Disclosed is a multiplexer that can be easily reconfigured, in the sense that the number of channels can be reduced or expanded by replacing the filters with suitable reactive loads and vice-versa. Although such loads are easy to manufacture, they are designed in such a way that the electrical characteristics of the remaining reconfigurable multiplexer maintains unaltered and additional tuning is not required. The present solution allows reducing both costs and losses of the branch by eliminating the circulators, although maintaining part of their flexibility.
