ABSTRACT:
A microwave detector arrangement operable over a broad range of frequencies including the series resonant frequency of a detector diode (9) for detecting microwave energy in a transmission line of characteristic impedance Z.sub.o, suitably a coplanar line. A first portion of line, including a strip conductor (3), is terminated by a network, including a capacitance (4) and a first resistance (5) in series with one another and with the parallel combination of a second resistance (6) and the diode (9). The capacitance (4) provides D.C. isolation, while the detector output is taken across a capacitance (10) in series with the diode (9). The first and second resistances (5,6) are respectively 2Z.sub.o /3 and 3Z.sub.o /2, so that the terminating impedance provides a reasonable match to the line over a broad frequency range.
