ABSTRACT:
A 180.degree. hybrid receptive of a fundamental frequency signal which may be adjusted over a range of frequencies produces the fundamental frequency signal at two output ports phased 180.degree. apart. Each of the output ports is coupled to a non-linear active device which produces the fundamental frequency and odd and even harmonics thereof. A 180.degree. and 0.degree. hybrid is coupled to receive at respective input ports the signal from the active devices and to produce at one output port all the odd harmonics and to produce at the other output port all of the even harmonics of the fundamental frequency. The even and odd harmonics of the fundamental frequency appearing at the two output ports of the 0.degree. and 180.degree. hybrid are isolated from one another.
