A microwave crosspoint blocking switch matrix and assembly (1) employing multilayer stripline and pin diode switching elements is employed to selectively electrically couple and decouple input transmission lines (2) to output transmission lines (4) without severance of the transmission lines and insertion of a series switch. The microwave crosspoint blocking switch matrix assembly employs pin diode arrays (6) coupled to input and output transmission lines at respective crosspoints (8). In order to route a signal from a specific input line to a selected output line, the pin diode array at the input/output transmission line crosspoint is activated and each transmission line is shorted at points one-quarter wavelength distant from the crosspoint to reflect, ideally, an infinite impedance at the interconnection point. Therefore, a desired signal cannot propagate in any direction except from the selected input line to the desired output line.
