A directional coupler (103) for radio equipment couples a radio frequency signal from an input of a microstrip trans- mission line (309) to an output and provides a directionally coupled output via a stripline microstrip (311). Open circuit micros- trip transmission line stubs (313 and 315) are tuned to a quarter wavelength of the third harmonic of the radio frequency to pro- vide third harmonic rejection within the directional coupler.
