Low Noise Preamplifier and Filter: An Approach to Problem Solving
IMP series low noise preamplifier, IMF series analog filter, IMG series mobile low noise power supply.
Essential for detecting weak signals are low-noise amplification and frequency band-limiting filters, which are also important in digital preprocessing. [Custom specifications available] Please consult us.
To detect weak signals, amplification is necessary, but for the signal not to be buried in noise, low noise in amplifiers is crucial. Since the amount of noise is proportional to the square root of the bandwidth, limiting the frequency bandwidth contributes to reducing noise. This product is portable, compact, lightweight, and excels in portability. While reducing noise solves many problems, appropriate processing for the desired challenges is necessary. Our company develops and manufactures products that approach noise reduction. We achieve better results through customization tailored to our customers' challenges. There are various methods for noise reduction, but here we introduce the IMP series low-noise preamplifiers, IMF series frequency bandwidth limiting filters, and IMG series mobile low-noise power supplies/adapters as approaches based on the fundamentals of low-noise amplification and frequency bandwidth limiting filters. We offer high performance that is easy for anyone to use, simple, eliminating unnecessary features and focusing on what is needed, with the capability to accommodate custom specifications for our customers. Proper analog signal processing reduces the processing burden on digital and software, enhancing overall performance. We are engaged in the development and design of electronic devices and measuring instruments that apply analog/digital signal processing. For more details, please refer to our catalog and website.

Applications/Examples of results
It can be used widely for various purposes. For example, mobile battery --> IMG241 --> IMP240/IMP242 --> (if necessary) IMF240 --> (data acquisition devices, etc.). When multiple configurations are connected in this way, they become completely isolated and independent low-noise amplification circuits. It allows for the detection of multiple micro-signals with low noise while avoiding mutual interference, and after amplification, it enables multi-channel acquisition with a single data collection device.

Company information
Our company is a proposal-based prototype development specialist manufacturer that develops custom electronic devices and the systems that connect them. We realize "measuring, thinking, and connecting" with unique ideas to meet our customers' needs. Please feel free to consult us about anything, whether it's "I want to make this," "I'm having trouble," or "I want to improve this." To materialize our customers' new ideas, we provide proposals and support through manufacturing. By using custom products that align with your company's values instead of fitting your values to off-the-shelf products, we lead you to high-value work. This enhances your company's value and increases productivity. It is our pleasure to respect diversity and provide and support such electronic devices. Sensors capture various phenomena, low-noise analog circuits process the reality as perceived by humans, digital signal processing performs analysis and feature extraction, and interfaces communicate the necessary results to people. The fields where we can apply our expertise in hardware/software signal processing are broad, and we continue to challenge ourselves in custom manufacturing and real-time processing based on our extensive development achievements and proprietary technologies.
