A transmitter including a frequency synthesizer with a voltage-controlled oscillator that provides an oscillating signal, a programmable delay circuit that delays the oscillating signal to provide a delayed oscillating signal, a power amplifier that is configured to amplify the delayed oscillating signal for transmission sufficient to produce interference, and a delay controller that programs the delay circuit with a delay time that reduces interference caused by coupling from the power amplifier to the voltage-controlled oscillator. The delay circuit may be programmed to reduce control voltage change of the voltage-controlled oscillator as a function of delay change, and/or to reduce phase noise degradation at an output of the transmitter as a function of delay change. The delay may be adjusted based on detected operating temperature. A calibration value may be determined at a calibration frequency, in which a frequency offset may be determined based on a selected channel frequency.

System and method of mitigating interference caused by coupling from power amplifier to voltage-controlled oscillator

The present disclosure relates to systems and methods for detecting anomalies in a semiconductor processing system. According to certain embodiments, one or more external sensors are mounted to a sub-fab component, communicating with the processing system via a communication channel different than a communication channel utilized by the sub-fab component and providing extrinsic sensor data that the sub-fab component is not configured to provide. The extrinsic sensor data may be combined with sensor data from a processing tool of the system and/or intrinsic sensor data of the sub-fab component to form virtual sensor data. In the event the virtual data exceeds or falls below a threshold, an intervention or a maintenance signal is dispatched, and in certain embodiments, an intervention or maintenance action is taken by the system.
