Abstract: RF front end circuitry includes mid/high-band switching circuitry and a carrier-aggregation diplexer. The mid/high-band switching circuitry is configured to receive and selectively route mid-band and high-band signals between a mid/high-band output port and a number of mid/high-band transceiver ports. The carrier-aggregation diplexer is coupled to a first one of the mid/high-band transceiver ports. Further, the carrier-aggregation diplexer is configured to pass mid-band signals between a mid-band diplexer port and the first one of the mid/high-band transceiver ports while attenuating other signals, and pass high-band signals between a high-band diplexer port and the first one of the mid/high-band transceiver ports while attenuating other signals.

Abstract: 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.

Abstract: RF front end circuitry includes primary transceiver circuitry associated with a primary antenna and secondary receiver circuitry associated with a secondary antenna. Generally, the primary transceiver circuitry and the primary antenna are located on one end of a mobile communications device, while the secondary receiver circuitry and the secondary antenna are located at an opposite end of the device. Cross-coupling connection lines run between the antenna switching circuitry for the primary antenna and the secondary antenna, and are reused to send a portion of primary RF transmit signals from the primary transceiver circuitry to the secondary receiver circuitry so that primary RF transmit signals coupled into the secondary receiver path via antenna-to-antenna coupling can be reduced.

Abstract: 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.

Abstract: In one embodiment, a balanced to unbalanced transformer utilizes a crossover configuration such that some portion of the secondary coil (inductor) is shared between two resonators (capacitors). Adding a first capacitor in parallel with a portion of the secondary inductor creates a first harmonic trap (filter), and also efficiently uses the secondary coil (inductor) as a resonating element.Adding a second capacitor which shares (crossover configuration) a portion of the secondary inductor with the first capacitor creates a second harmonic trap (filter), which may be tuned to the same harmonic as the first harmonic trap, or may be tuned to a different harmonic.

Abstract: Switchable capacitive elements are disclosed, along with programmable capacitor arrays (PCAs). One embodiment of the switchable capacitive element includes a field effect transistor (FET) device stack, a first capacitor, and a second capacitor. The FET device stack is operable in an open state and in a closed state and has a plurality of FET devices coupled in series to form the FET device stack. The first capacitor and the second capacitor are both coupled in series with the FET device stack. However, the first capacitor is coupled to a first end of the FET device stack while the second capacitor is coupled to a second end opposite the first end of the FET device stack. In this manner, the switchable capacitive element can be operated without a negative charge pump, with decreased bias swings, and with a better power performance.
