Patent ID: 8224234

Claim:
A jamming system comprising: a plurality of digital signal generators each of which generates a pair of digital quadrature signals; a plurality of digital filters, each of the plurality of digital filters having inputs coupled to receive a pair of digital quadrature signals from a corresponding one of said plurality of digital signal generators and to provide filtered quadrature digital signals at a pair of outputs thereof; a plurality of quadrature digital-to-analog (D/A) converter pairs, each of said plurality of quadrature D/A converters pairs disposed to receive one or more independent pairs of filtered quadrature jamming signals from a corresponding one or more of said plurality of digital filters and to provide one or more independent quadrature signal spectrum pairs at a pair of outputs thereof; a plurality of quadrature modulators, each of said plurality of quadrature modulators having a first port coupled to receive a first one of the quadrature pairs of analog quadrature signal spectrums from a corresponding one of said quadrature D/A converters, having a second port coupled to receive a second one of the pair of analog quadrature signal spectrums from the corresponding one of said quadrature D/A converters, having a third port configured to receive a local oscillator signal and having an output port at which an output signal is provided; a plurality of amplifiers, each of said amplifiers having an input port coupled to one or more output ports of a corresponding one or more of said plurality of quadrature modulators and having an output port coupled to the output of the jamming system.
