    摘要: The invention is a balun transformer that converts a single-ended (or unbalanced) signal to a differential (or balanced) signal. The balun is a printed metal pattern on a circuit board in conjunction with several low cost chip capacitors and a low cost chip inductor. The balun transformer is a modified Marchand balun that is implemented using printed transmission lines. The balun has a plurality of coupled transmission lines to improve tolerances to variations in PC board fabrication. To make the balun compact, it is electrically lengthened through the use of capacitive loading, which reduces the required physical size. Additionally, the capacitors increase the bandwidth due to the resonant interaction between the short inductive balun and the capacitors that are placed in series with the input and the output.

    摘要: A printed bandpass filter is mounted on a precision substrate to eliminate the need for post-fabrication tuning. The filter input is capacitively coupled to a series of quarter wavelength resonators and the filter output. The quarter wavelength resonators are printed as spirals to reduce filter size. The resonators define the bandpass characteristics of the filter. The filter also weakly couples the input signal to the filter output in a manner to cancel the signal image. Mechanical clips mitigate thermal stress on solder connections when the precision substrate is mounted on a second printed circuit board.

    摘要: A Variable Gain Amplifier (VGA) amplifies an input signal according to a gain, to produce an amplified signal. A detector module detects a power indicative of a power of the amplified signal. A comparator module compares the detected power to a high threshold, a low threshold and a target threshold intermediate the high and low thresholds. A controller module changes the gain of the VGA so as to drive the detected power in a direction toward the middle threshold when the comparator module indicates the detected power is not between the high and low thresholds.

    摘要: A method and system for monitoring and compensating the performance of an operational circuit is provided. The system includes one or more integrated circuit chips and a controller. Each integrated circuit chip includes one or more operational circuits, each operational circuit having at least one controllable circuit parameter. Each integrated circuit chip also includes a process monitor module at least partially constructed thereon. The controller is coupled to each process monitor module and to each operational circuit. The controller includes logic for evaluating the performance of an operational circuit based on data obtained from process monitor module and operational circuit related data stored in a memory. Based on the evaluation, the controller determines whether any deviations from desired or optimal performance of the circuit exist. If deviations exist, the controller generates a control signal to initiate adjustments to the operational circuit to compensate for the deviations.
