A delay filter module comprising at least one dielectric monoblock ceramic band pass filter and a circuit for compensating/equalizing the signal delay produced by the delay filter. In one embodiment, the circuit is defined by a hybrid coupler defining at least two ports coupled to a dielectric ceramic reactive termination block defining at least a pair of reactive termination resonators and coupling capacitors. The delay can be adjusted by tuning the dielectric monoblock band pass filter and/or the reactive termination resonators and/or the coupling capacitors defined by the dielectric ceramic reactive termination block.
