摘要： A method (140) for tuning millimeter-wave FET amplifiers (20) during manufacture, through the application (144) of a gate bias voltage (52) so as to tune the FET (22) of the amplifier (20) to match an input circuit (24), and through the application (146) of a drain bias voltage (74) so as to tune the FET (22) of the amplifier (20) to match an output circuit (26), then measuring (150) the frequency response of the amplifier (20). This tuning method (140) is repeated (152) until a predetermined frequency response has been achieved. Once achieved, the predetermined frequency response is realized (154) by permanently fixing the gate bias voltage (52) and the drain bias voltage (74) at the determined values. This iterative method (140) of tuning amplifiers (20) is then repeated for all amplifiers (20) to be tuned.

摘要： A power amplifier (10) suitable for satellite cellular communication systems provides highly efficient linear amplification of noise-like RF signals that have multiple carriers spread over a large instantaneous bandwidth. The amount of distortion present in the output is detected (14, 16, 18) and a feedback signal is provided to control the bias point of the active devices. As drive levels increase, the increased harmonic distortion power detected causes the power amplifier bias to increase thus reducing distortion. The control circuit (20) continually re-biases the power amplifier (12) for maximum efficiency for a predetermined level of distortion. The control circuit (20) may be adjusted to maximize efficiency while maintaining an allowable distortion level over the entire dynamic range of the devices.

摘要： A system for switching radio frequency signals from an input side (5, FIG. 1 ) to an output side (6) can be used to combine multiple input signals to form a single output and to distribute a single input signal to form multiple outputs. Gain correction amplifiers (20, 25) are employed to adjust the overall gain of a particular column and row of the switch matrix which minimizes the effect of variations in the gain of the amplified switching elements (30) which perform the switching function. Resistive matching units (70, FIG. 2) provide coupling to and from the amplified switching elements (30) without substantially changing the characteristic impedance of the input and output paths.

摘要： An K-band amplifier circuit (10) with two samplers (12, 18) coupled to detectors (22, 26) that detect an input and an output RF signal level. These two reference signals are provided to a differential gain control circuit (24) which is coupled to one or more variable gain amplifier (VGA) (14) stages. The VGAs compensate for the gain of an entire chain of amplifiers (16). When the individual amplifier gains vary for any reason, (i.e., process, temperature effects or end of life degradation) the variation in gain causes higher or lower levels of detected output reference signals for a given RF input signal. The gain control circuit (24) drives the VGA (14) up or down as appropriate. By maintaining a constant offset in input and output reference control signals, the gain control circuit (24) drives the amplifier chain (16) to a constant gain.

摘要： An integrated microstrip (14) to suspended stripline (24) transition structure and method for fabricating the same provide a transition from microstrip (14) to suspended stripline (24) transmission line with minimal electrical discontinuity and insensitivity due to misalignment. A conductor (10) has a constant width, while gradually tapering voids (44,42) in ground planes (36, 38) provide a suspended stripline (24) transmission medium. The gradually tapering voids (44, 42) provide impedance transformation and minimize discontinuities during transition due to fabrication tolerances.

摘要： A MMIC power amplifier (100) uses MMIC FET cells (104, 112) and provides high gain at microwave and millimeter-wave frequencies. The power amplifier includes an input matching network (102), a first plurality of unit FET cells (104) for amplifying in-phase signals provided by the input matching network, a second plurality of unit FET cells (112), an interstage matching network (106) for combining output signals provided by the first plurality of unit FET cells, and providing in-phase signals to the second plurality of unit FET cells; and a combiner (113) for combining output signals of the second plurality of unit FET cells to provide an output signal. The FET cells are designed to be unconditionally stable without the use of an external series gate resistance. The FET cells are combined to provide total device periphery suitable for output power levels exceeding 0.8 watt at frequencies ranging from 19 to 23.5 GHz. The FET cells are designed using device scaling and device modeling techniques. The power amplifier is suitable for applications where high efficiency and high gain are important, such as satellite communication systems.
