  • Patent number: 6154641
    Abstract: A wideband multiple channel frequency converter includes a mixer, a frequency generator for generating a local oscillator signal, a power divider for receiving the local oscillator signal and providing a portion of the signal to the mixer and a portion of the signal to a feed forward path which phase and amplitude adjusts the signal and a power combiner for receiving and combining a signal from the mixer and the phase and amplitude adjusted signal from the feed forward path. In addition, an attenuator may be implemented to reduce a power level of a signal to be converted and a band-pass filter may receive the signal from the power combiner. The converter compensates for local oscillator signal leakage and can reduce inter-modulation components.
