摘要： Apparatus and associated methods relate to a low-noise wideband active phase shifter. The low-noise wideband active phase shifter includes first and second transconductance cells, a fixed LC series network and a tunable LC series network configured to form an all-pass lattice network. The first and second transconductance cells, each include a transistor, a feedback network, and a transistor biasing network. The transistor has an input terminal and an output terminal. The negative feedback network electrically couples the input and output terminals of the transistor. The biasing network provides input and output biasing of the transistor. The fixed LC series network connects between the first and the second transconductance cells. The tunable LC series network connects between the first and the second transconductance cells.

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.

摘要： A reconfigurable filter includes a splitter for providing an input signal on a plurality of paths. A first path includes a first filter section that can be configured as either a tunable band pass filter with a shunt-connected fixed inductor or a tunable notch filter with a fixed inductor in parallel with a tunable varactor, either of which can be responsive to a control signal. A second path is an all pass section that provides an unfiltered signal. A combiner is provided for combining the first filtered signal with the unfiltered signal for producing a composite signal. The unfiltered signal can have its gain or phase modified in either or both the splitter or the combiner.
