Optoelectronic Filter and Method for Signal Suppression

In the fields of telecommunications and electronics, handling different radio-frequency (RF) signals efficiently is of utmost importance. As the number of devices and communication channels increases, the risk of signal interference also grows exponentially. Particularly with RF signals of differing power levels, the stronger signals can easily overpower weaker ones, leading to unbalanced outputs and reduced transmission quality. The existing frequency filters struggle with this situation. They often fail to effectively check the interference between RF signals of different power levels, often leaning toward the more powerful signals and thus diminishing the impact of weaker ones. This biased imbalance introduces noise into the telecommunication system, resulting in decreased performance. Hence, there is a pressing need for a solution that handles RF signals of varying power levels effectively, reducing interference and ensuring a more balanced output.

Technology Description

This invention is an optoelectronic filter designed to balance different RF signals. The filter comes equipped with a modulator circuit with first and second inputs. The first input receives two RF signals with different power levels and subsequently generates a modulated signal at the output. Crucially, the first RF signal in the modulated output is suppressed relative to the second, fine-tuning the balance between varying frequency signals. Additionally, the filter includes a light source connected to the second input of the modulator. The standout feature of this invention is the differential suppression of RF signals, enabling the filter to handle frequency signals of varying power more effectively. The inclusion of a modulator circuit that manages RF signals and a light source adds to its versatility. The ability to suppress stronger signals ensures a more balanced output signal, reducing the chances of one signal overpowering others — a differentiating factor in the crowded space of electronic filters.
