摘要： An apparatus for controlling a power amplifier configured to amplify radio frequency (RF) signal includes a detector and a controller. The detector is configured to detect a power level of the RF signal with respect to a predetermined power threshold and to generate a corresponding detection signal. The controller is configured to provide a control voltage to an output transistor of the amplifier based on the detection signal. The control voltage has a low voltage value, which is substantially the same as a value of a supply voltage, when the detection signal indicates that the power level is below the power threshold, and the control voltage has a high voltage value when the detection signal indicates that the power level is above the power threshold. The controller generates the high voltage value by boosting the supply voltage.

摘要： A mixer includes a first field effect transistor (FET) having a gate that receives a first signal of a balanced local oscillator (LO) signal, a first source/drain coupled to a ground voltage, and a second source/drain; and a second FET having a gate that receives a second signal of the balanced LO signal, a first source/drain that floats, and a second source/drain connected to the second source/drain of the first FET to form a mixing node, the second signal being out of phase with the first signal. A diplexer is connected between the mixing node and each of a radio frequency (RF) port and an intermediate frequency (IF) port. A first LO leakage caused by the first FET is substantially canceled by a second LO leakage caused by the second FET at the mixing node.

摘要： A mixing method and mixer structure provide a circuit topology suitable for use in radio receivers, transmitters, tuners, instrumentation systems, telemetry systems, and other systems and devices performing frequency conversion in either homodyne or heterodyne implementations. The inventive mixer may be used for wireless communication devices including radios, cellular telephones, and telemetry systems whether land, sea, airborne, or space based, and whether fixed or mobile. The mixer provides superior intermodulation and harmonic distortion suppression and features excellent conversion loss, noise figure, port match, and port isolation as a result of its circuit topology. The mixer device circuit combines the advantages of series mixing FETs, a triple balanced design using a balanced passive reflection transformer, a precise local oscillator phase splitter, and square wave gate drive having high slew rate signal characteristics to achieve high levels of performance. It is power conservative and offers the advantage of long battery life in portable devices such as portable radios and cellular telephones as it requires only a modest amount of DC and local oscillator drive power, and is useful for operation over at least a multi-decade bandwidth.

摘要： A high dynamic range mixer apparatus and mixing method where a wide high dynamic range is achieved in part due to the use of a series pair of switching devices that are matched so as to afford complete or substantial cancellation of nonlinearity distortion. The inventive structure and method preserves the compensation and cancellation mechanism of the series pair of back-to-back connected FETs without the need for either of an intermediate frequency (IF) balun or a radio-frequency (RF) balun. Typically, the switching devices are PETs, such as for example MESFETs, connected source-to-source with one drain terminal grounded, and a non-grounded or floating switching signal applied between the common gate and common source terminals.
