3dB bandwidth: High-performance high-pass filter from 150kHz to 3GHz
A 150 kHz high-pass filter protects the RF input of a spectrum analyzer or EMI receiver from residual 50 Hz voltage in high-amplitude subharmonics and conductive emission measurement setups.
It is a filter designed to transmit light in two specific wavelength bands while blocking (preventing) other wavelength bands. It is ideal for surveillance cameras and similar applications.
1) Are you facing such issues? ■ Is it possible to transmit visible light and part of the infrared wavelength (850nm)? ■ I want to ensure that the blocking range that causes noise is definitely cut off. ■ Since there is a range of incident angles, can this be taken into account? ■ The shape is special; can it be shipped as a component? 2) Dual-band pass filter (multi-band pass filter) This is a filter designed to transmit light in two specific wavelength bands while blocking (preventing) other wavelength bands. In addition to standard IR cut, it has the function of selectively transmitting only specific near-infrared wavelengths (such as 850nm, 905nm, 940nm, 1064nm). For example, it is ideal for applications that require monitoring both during the day and at night by transmitting specific visible light and specific near-infrared light. With 40 years of experience, we have achieved sharp wavelength separation and high transmission rates. Our unique control technology during film formation allows for high durability and reduced shift.

Supports 150M/260M/400M band for business use wireless bandwidth.
When measuring harmonics generated from devices such as radios with a spectrum analyzer (specan), the analyzer itself can generate harmonics by receiving the fundamental wave, which can lead to significant measurement errors, especially when measuring low-level harmonics. This high-pass filter for harmonic measurement removes the fundamental wave and allows harmonics to pass through, thereby reducing the input of the fundamental wave to the spectrum analyzer and also decreasing the harmonics generated by the analyzer. This product can be used as a measurement auxiliary device to improve accuracy. 【Features】 - Compatible with 150M/260M/400M band commercial radio frequencies - Attenuates the fundamental wave frequency band by over 40dB - High input capability: 30W For more details, please contact us or download the catalog.

We implemented three different methods for surface treatment of the internal flow path. As a result, we realized the desired shape and advanced the research with three types of waveguides featuring different surface treatments. Following the research results, a request for a new prototype was made. 【Case Overview (Partial)】 ■ Issue - A waveguide (a metal pipe that transmits electromagnetic waves) is needed to accurately and evenly transmit fine electromagnetic waves. ■ Requests - We want to achieve a complex structure. - We would like to request 3D data design as well. - We want to manufacture a high-performance waveguide. *For more detailed information about the case, please refer to the related link.
