Patent ID: 8706052

Claim:
A wideband harmonic signal generator comprising: a programmable frequency generator for generating a signal having a selected fundamental frequency; a harmonic series generator arranged to receive the signal having the selected fundamental frequency and to produce a signal having a harmonic series, wherein the harmonic series includes harmonics of the selected fundamental frequency; a wideband impedance matching network that is arranged to receive the signal having the harmonic series and to transfer the signal having the harmonic series using a balanced impedance output; a directional antenna having a characteristic impedance that is matched to the balanced impedance output and that is arranged to receive and directionally transmit the transferred signal having the harmonic series; a housing that is arranged as a hand-held assembly to which the programmable frequency generator, the harmonic series generator, the wideband impedance matching network, and the directional antenna are mounted; and an RF switch having an input that is coupled to receive the signal having a selected fundamental frequency, the RF switch arranged to couple the input to a first output that is selectively coupled to the directional antenna when a bypass path is selected, and the RF switch arranged to selectively couple the input to a second output that is coupled the harmonic series generator when a harmonic generator frequency path is selected.
