In the present technique for transmitting and delaying radio frequency signal transmission, an RF delay filter (102) is provided with at least one high permittivity material coaxial delay element (104) with each having an input port (114) and an output port (116). Multiple coaxial delay elements are operably coupled by a quarter-wave microstrip transmission line (230) to offset any frequency mismatch at the band edges of the delay elements. A series of capacitors (126, 128) are also included at each port of the coaxial elements to compensate for any resultant parasitic inductance.
