Abstract:
A transceiver apparatus on a printed circuit board (PCB) comprising:a first probe for being excited with received signals in a first frequency range and coupling said received signals to receive circuitry, said first probe oriented in a first position;a second probe coupled to transmit circuitry for generating, through excitation, transmit signals in a second frequency range, said second probe oriented orthogonal to said first probe such that said transmit signals are polarized essentially orthogonally with respect to said receive signals;an enclosed waveguide structure positioned between said first and second probes, said enclosed waveguide structure having first and second ends, a top closed portion, and a bottom open portion, said bottom open portion being fixedly attached to said PCB so as to form an enclosed waveguide area;wherein said first end of said enclosed waveguide structure is positioned over an opening in said PCB and one of said first and second probes is positioned at said opening, said other one of said first and second probes is positioned at said second end of said enclosed waveguide structure, and said enclosed waveguide structure provides frequency isolation between said transmit and received signals.
