Abstract: Differential power amplifier circuitry includes a differential transistor pair, an input transformer, and biasing circuitry. The base contact of each transistor in the differential transistor pair may be coupled to the input transformer through a coupling capacitor. The coupling capacitors may be designed to resonate with the input transformer about a desired frequency range, thereby passing desirable signals to the differential transistor pair while blocking undesirable signals. The biasing circuitry may include a pair of emitter follower transistors, each coupled at the emitter to the base contact of each one of the transistors in the differential transistor pair and adapted to bias the differential transistor pair to maximize efficiency and stability.

Abstract: This disclosure relates to radio frequency (RF) power converters and methods of operating the same. In one embodiment, an RF power converter includes an RF switching converter, a low-drop out (LDO) regulation circuit, and an RF filter. The RF filter is coupled to receive a pulsed output voltage from the RF switching converter and a supply voltage from the LDO regulation circuit. The RF filter is operable to alternate between a first RF filter topology and a second RF filter topology. In the first RF filter topology, the RF filter is configured to convert the pulsed output voltage from a switching circuit into the supply voltage. The RF filter in the second RF filter topology is configured to filter the supply voltage from the LDO regulation circuit to reduce a ripple variation in a supply voltage level of the supply voltage. As such, the RF filter provides greater versatility.

Abstract: A baseband PA predistortion module, which includes a baseband combiner, a baseband PA correction circuit, and a baseband filter, is disclosed. The baseband PA correction circuit replicates behavior of an RF PA by processing a modulation data signal to provide a predistortion data signal. The behavior of the RF PA includes distortion. The modulation data signal is representative of an RF input signal to an RF PA and the predistortion data signal is representative of a correction needed at an output of the RF PA. The baseband filter receives and filters the predistortion data signal to provide a reduced predistortion data signal, such that a low frequency content of the reduced predistortion data signal is less than a low frequency content of the predistortion data signal. The baseband combiner receives and combines the modulation data signal and the reduced predistortion data signal to provide a baseband transmit signal.

Abstract: Antenna tuning circuitry includes an antenna tuning node, an antenna tuning switch, and a resonant tuning circuit. The antenna tuning node is coupled to a resonant conduction element of an antenna. The antenna tuning switch and the resonant tuning circuit are coupled in series between the antenna tuning switch and the antenna tuning node, such that the resonant tuning circuit is between the antenna tuning node and the antenna tuning switch. The resonant tuning circuit is configured to resonate at one or more harmonic frequencies generated by the antenna tuning switch such that a high impedance path is formed between the antenna tuning switch and the antenna tuning node at harmonic frequencies generated by the antenna tuning switch. Accordingly, harmonic interference generated by the antenna tuning switch is prevented from reaching the antenna, while simultaneously allowing for tuning of the antenna.
