Abstract: The present disclosure relates to a reconfigurable directional coupler with a variable coupling factor that can be changed in value as a function of a desired transmit band of operation. The reconfigurable directional coupler includes a primary inductive segment, secondary inductive segments, and switch circuitry configured to change the total coupling capacitance formed between the primary and secondary inductive segments by selectively switching the secondary inductive segments into the secondary signal path. Simultaneously, the mutual inductance and coupling factor between the primary and the secondary inductive segments are reconfigured.

Abstract: RF circuitry, which includes a first main RF switching circuit and a second main RF switching circuit, is disclosed. The first main RF switching circuit is capable of providing an RF signal path between a first main RF port and a first selected one of a first RF antenna and a second RF antenna. The second main RF switching circuit is capable of providing an RF signal path between a second main RF port and a second selected one of the first RF antenna and the second RF antenna. The first main RF switching circuit includes a first pair of RF switches coupled in series between the first RF antenna and the first main RF port; a second pair of RF switches coupled in series between the second RF antenna and the first main RF port; a first shunt RF switch; and a second shunt RF switch.

Abstract: Tank circuitry coupled to the output terminals of a differential power amplifier includes two trap circuits configured to divert harmonic signals away from the output terminals. A tank inductor is provided to form a tank circuit in conjunction with each one of the trap circuits. At certain harmonic frequencies of the input signal to the differential power amplifier, the trap circuits are resonant and present a substantially low impedance path to ground, thereby diverting harmonic signals away from the output terminals of the differential power amplifier. At the fundamental frequency of the input signal to the differential power amplifier, the trap circuits are resonant with the tank inductor and present a substantially high impedance compared to the load impedance presented at the output terminals of the differential power amplifier, thereby reducing the loading effect of the trap circuits at the fundamental frequency.
