<p>A resistor tuning network comprises a resistor ladder including a plurality of resistor rungs each comprising a first resistance R and a second resistance 2R. The second resistance of each resistor rung in the plurality is connected to a switching arrangement. A respective switching arrangement is controllable to connect the respective second resistance to either a positive side αVs of a differential signal or the negative side αVs of the differential signal. The tuning network may be used in a duplexer for a radio frequency transceiver.</p> |
