  • Filters for multi-band wireless device
    Patent number: 9692392
    Abstract: Techniques to implement a filter for a selected signal path by reusing a circuit component in an unselected signal path are disclosed. In an exemplary design, an apparatus includes first, second, and third circuits. The first circuit passes a first radio frequency (RF) signal to an antenna when a first signal path is selected. The second circuit passes a second RF signal to the antenna when a second signal path is selected. The third circuit is selectively coupled to the first circuit, e.g., via a switch. The first and third circuits form a filter for the second RF signal (e.g., to attenuate a harmonic of the second RF signal) when the second signal path is selected and the first signal path is unselected. The first circuit may include a series inductor, and the third circuit may include a shunt capacitor.
