摘要： Radio-frequency (RF) switch circuits are disclosed providing improved switching performance. An RF switch system typically includes a plurality of field- effect transistors (FETs) connected in series between first and second nodes, with each FET having a gate, a source, a drain and a body. Disclosed are, among others, various examples of circuits that couple different portions of a FET and/or different FETs to yield desirable performance improvements for RF switch systems. In some embodiments, one or more features of a given example can provide such performance improvements. In some embodiments, features from different examples can be combined to yield such performance improvements.

摘要： pHEMT-based circuits and methods of improving the linearity thereof. One example pHEMT circuit includes a pHEMT connected between an input terminal and a load and a non-linear resistance connected to the pHEMT. The pHEMT produces a first harmonic signal at the load responsive to being driven by an input signal of a fundamental frequency received at the input terminal, the first harmonic signal having a first phase. The non-linear resistance has a resistance selected to produce a second harmonic signal at the load having a second phase opposite to the first phase. Methods can include determining a first amplitude and a first phase of a first harmonic signal produced at the load by a pHEMT in an ON state, and tuning the non-linear resistance to produce at the load a second harmonic signal having a second amplitude and a second phase that minimizes a net harmonic signal at the load.

摘要： An exemplary coupler detector circuit comprises a coupler, a detector circuit, and a harmonic tank. The coupler has a transmission line electromagnetically coupled to a coupled line, and the coupled line has an isolated node and a coupled node. The transmission line may, for example, be a 50 ohm RF line for transmitting RF energy. The detector circuit is connected to the coupled node and is configured to detect a power transmitted along the transmission line. The harmonic tank is connected to the coupled node, and is configured to short to ground at least one harmonic signal transmitted along the coupled node.
