摘要： A tunable diplexer includes a high pass filter, a low pass filter, a high band port, a low band port, and an antenna port. The high pass filter is adapted to pass high band signals falling within a high pass band between the high band port and the antenna port, while attenuating signals outside of the high pass band. The low pass filter is adapted to pass low band signals falling within a low pass band between the low band port and the antenna port, while attenuating signals outside of the low pass band. The low pass filter includes a low stop band zero, which is adapted to attenuate signals within a low stop band. The low stop band zero is tunable, such that the low stop band can be adjusted to selectively attenuate signals within a given frequency band in the low pass band.

摘要： This disclosure includes embodiments of a tunable hybrid coupler. The tunable hybrid coupler includes a first inductive element having a first inductance, a second inductive element having a second inductance and mutually coupled to the first inductive element, a first variable capacitive element having a first variable capacitance, and a second variable capacitance having a second variable capacitance. The first variable capacitive element is coupled between a first port and a second port. The second variable capacitive element is coupled between a third port and a fourth port. The first inductive element is coupled from the first port to the third port, while the second inductive element is coupled from the second port to the fourth port. Accordingly, the tunable hybrid coupler may form an impedance matching network that is tunable to different RF communication bands. The tunable hybrid coupler may thus be included in a tunable RF duplexer.

摘要： Embodiments of radio frequency (RF) filtering circuitry are disclosed. In one embodiment, the RF filtering circuitry includes a first port, a second port, a first RF filter path, and a second RF filter path. The first RF filter path is connected between the first port and the second port and includes at least a pair of weakly coupled resonators. The weakly coupled resonators are configured such that a first transfer response between the first port and the second port defines a first passband. The second RF filter path is coupled to the first RF filter path and is configured such that the first transfer response between the first port and the second port defines a stopband adjacent to the first passband without substantially increasing ripple variation of the first passband defined by the first transfer response.

摘要： Embodiments of an apparatus are disclosed that includes a first three dimensional (3D) inductor and a second 3D inductor. The first three dimensional (3D) inductor has a first conductive path shaped as a first two dimensional (2D) lobe laid over a first 3D volume. In addition, the second 3D inductor has a second conductive path, wherein the second 3D inductor is inserted into the first 3D inductor so that the second conductive path at least partially extends through the first 3D volume. Since second 3D inductor is inserted into the first 3D inductor, the 3D inductors may be coupled to one another. Depending on orientation and distances of structures provided by the 3D inductors, the 3D inductors may be weakly or moderately coupled.

摘要： This disclosure relates to radio frequency (RF) front end circuitry used to route RF signals. In one embodiment, the RF front end circuitry has a filter circuit and a switch device. The switch device includes a common port, an RF port, and switchable path connected in series between the common port and the RF port. The switch device is configured to present approximately the filter capacitance of the filter circuit at the common port when the switchable path is closed. However, when the switchable path is open, the switch device is configured to present a device capacitance at the common port that is approximately equal to the filter capacitance of the filter circuit. In this manner, if the common port is connected to an antenna, the capacitance seen by the antenna from the common port remains substantially unchanged regardless of which of the switchable path is opened or closed.

摘要： The present disclosure relates to a tunable slow-wave transmission line. The tunable slow-wave transmission line is formed in a multi-layer substrate and includes an undulating signal path. The undulating signal path includes at least two loop structures, wherein each loop structure includes at least two via structures connected by at least one intra-loop trace. The undulating signal path further includes at least one inter-loop trace connecting the at least two loop structures. The tunable slow-wave transmission line includes a first ground structure disposed along the undulating signal path. Further, the tunable slow-wave transmission line includes one or more circuits that may alter a signal transmitted in the tunable slow-wave transmission line so as to tune a frequency of the signal.
