  • High-performance conversion between single-ended and differential/common-mode signals
    Patent number: 10483940
    Abstract: A signal conversion apparatus includes first and second input ports and first and second output ports. A first splitter is coupled to convert a first single-ended signal received on the first input port into a differential signal including first and second opposite-phase components, and to provide the first and second opposite-phase components respectively on the first and second output ports. A second splitter is separate from the first splitter and is coupled to convert a second single-ended signal received on the second input port into a common-mode signal including first and second in-phase components, and to provide the first and second in-phase components respectively on the first and second output ports together with the first and second opposite-phase components.

  • Efficient reduction of local oscillator leakage
    Patent number: 8744385
    Abstract: A frequency conversion system includes a mixer, which is coupled to mix an input signal with a Local Oscillator (LO) signal, so as to produce an output signal. Control circuitry is configured to adjust an actual level of the LO signal provided to the mixer, so as to maintain the actual level substantially constant. A nulling signal generator is coupled to inject a nulling signal into the input signal prior to mixing with the LO signal adjusted by the control circuitry.
