Abstract: Techniques for efficiently integrating directional coupler circuitry with other circuit elements of an RF front end. In an aspect, one or more inductors of an RF front end filter is incorporated into a first inductor of the directional coupler, and a capacitor is further coupled in parallel with the first inductor. In another aspect, circuitry associated with matching components of the RF front end may further be incorporated into the directional coupler design. Further techniques are provided for coupling directivity tuning elements to a second inductor of the directional coupler to improve the linearity of the coupler over other tuning techniques.

Abstract: Techniques for improving the linearity of radio-frequency (RF) front-end switches. In an aspect, open-loop techniques are disclosed for superimposing the output voltage of one or more negative rectifiers on a negative substrate bias voltage to reduce the non-linearities associated with voltage-dependent substrate leakage current. In another aspect, closed-loop techniques are further disclosed for maintaining the substrate bias voltage close to a reference voltage. Exemplary embodiments of the circuit blocks are further described.
