摘要： A method and frequency converter for a radio rapid frequency signal scanning and including a local oscillator signal synthesis source (112) producing a local oscillator signal (502) with local oscillator bursts (210). The local oscillator bursts (210) contain pulse width modulated RF frequency pulses (602). Each local oscillator burst having, for a pre-determined duration, RF frequency pulses within an effective amplitude above a pre-determined threshold (260). Each local oscillator burst (210) having also has effective amplitude pulse shaping envelope (504) that reduces at least one frequency domain component magnitude (310) of the local oscillator signal (300). A radio frequency mixer (110) receives an RF signal input (104) and the local oscillator signal to produce an output signal (160) at a frequency related to a combination of a frequency of the RF signal input and a frequency of the local oscillator signal.

摘要： A high efficiency amplifier arrangement consistent with certain embodiments of the invention has an amplifier (104) that receives an input signal and amplifies the input signal to produce an output signal that drives a load (108). A variable impedance transformer (300) is disposed between the amplifier (104) and the load (108) to presents a varying load impedance to the output of the amplifier (104). A control mechanism, such as a programmed processor (604, 504), controls the variable impedance transformer (300) with a control signal so that the load impedance seen by the amplifier (104) varies in accordance with an envelope of the input signal. The control signal varies the load impedance in a manner that keeps the output of the amplifier (104) near a peak value. The arrangement may further include a circuit for controlling a DC input bias (420) of the amplifier (104) to keep the amplifier (104) operating within a predetermined class of operation throughout a range of input signals. The control signal may be calculated, looked up in a lookup table (610) or derived from an envelope detector (404).

摘要： A structure and method for the improvement of interference isolation using distributed broadband technology. This structure uses signal processing across a distributed network in order to optimize the isolation of a signal of interest when noise, interference and crosstalk signal sources are present. The structure is designed so that a signal arrives at a node in the network via more than one path and is summed in a correlated or in-phase manner. Each signal path is designed so that the signal phase may be modulated to create the in-phase summing. Noise sources that arrive at the network node are added in an uncorrelated or out-of-phase manner. Therefore, the combination of the signal adding coherently and the interference adding with an uncorrelated phase improves the signal to interference ratio. This type of structure may be applied in an RF power amplifier application in order to provide an improved interference or crosstalk signal ratio.

摘要： A radio frequency power amplifier circuit according to certain embodiments of the present invention uses a distributed radio frequency amplifier 110 having a plurality of stages each with an input. The distributed radio frequency amplifier 110 drives an output load, such as an antenna 114. A drive signal synthesizer 106, having a plurality of outputs, drives the plurality of inputs to the distributed amplifier 110. Changes in load impedance are measured, e.g., using a directional coupler 160, and the measurement is used to change a drive signal produced by the drive signal synthesizer 106 to compensate for the change in load impedance.

摘要： A feedforward amplifier and notch filter (150) according to the present invention uses a direct coupling of an amplifier stage (158) with the amplifier's load (RL). The main amplifier (202) is coupled through a transmission line (210) to the load. This direct coupled amplifier stage (158) is driven by an signal that induces a very low impedance in parallel with the load at the receive frequency, but appears as an open circuit at the desired frequencies so that the desired signal from the main amplifier is virtually unaffected while output components at the receive frequency are cancelled.

摘要： The invention produces an accurate quadrature relationship for a range of frequencies using passive components in the primary quadrature splitting circuits. A reference oscillator (202) generates a reference signal which is fed to a conventional passive quadrature splitter circuit (204). However, since the reference circuit provides signals over a range of frequencies, the output signals of the passive quadrature splitter may not have an accurate quadrature relationship. The output signals of the passive quadrature splitter are then equalized in magnitude, and the sum and difference of the signals are produced, which will be in an accurate quadrature relationship.

摘要： A three-dimensional inductor coil is fabricated on top of a semiconductor substrate. The fabrication process includes the steps of depositing a first photoresist layer (406), forming a trench therein, and filling the trench with electroplated metal (404). A second photoresist layer (408) is deposited, and first and second trenches (410) are formed therein and filled with electroplated metal (412). A third photoresist layer (416) is deposited and a trench (418) formed therein, and then filled with electroplated metal (420). The first, second, and third photoresist layers (406, 408, 416) are then removed to expose a multi-loop inductor coil (500, 550).
