    摘要: Doherty and distributed amplifier (DA) designs are combined to achieve, wideband amplifiers with high efficiency dynamic range. A modified Doherty amplifier includes a wideband phase shifter providing first and second outputs, a main amplifier coupled to the first output, an auxiliary amplifier coupled to the second output, and a wideband combining network combining the outputs in phase. A multi-stage DA has a main output and a termination port, and a phase delay module and transforming network allowing power at the termination port to be combined in phase with power at the main output. In one combination, one or more stages of the DA may comprise a Doherty amplifier. In another combination, a modified series-type Doherty amplifying system is achieved by cascading main and auxiliary DAs. In any combination, Doherty topology may include a bias control module.

In another embodiment, multiple capacitive elements are connected to the spur. In an exemplary embodiment, the capacitively loaded spurline filter provides a band rejection frequency response similar to the band rejection frequency response of a similar spurline filter that does not comprise at least one capacitive element but the capacitively loaded spurline filter has half the layout area or less. In an exemplary embodiment, the spurline filter comprises capacitive elements, where the capacitive elements are configured to reduce the resonant frequency of the filter.

    摘要: Contrary to phase shifters which require complimentary polarity control voltages, a phase shifter may be driven with a single polarity control voltage. The phase shifter comprises an input node in communication with both a high pass network and a low pass network which are both in communication with an output node, where the phase shifter further comprises a first single pole double throw switch and a second single pole double throw switch configured to selectively pass an RF signal from the input node to the output node by way of one of said high pass network and said low pass network. Furthermore, the first and second single pole double throw switches are configured to select between the high pass network and the low pass network based on a single control signal having a voltage greater than or less than a reference voltage.
