[Case Study] Front-End Module for Phased Array Radar

[Case Study] Front-End Module for Phased Array Radar

Light conversion section ~ AD/DA conversion section ~ Frequency conversion section ~ Antenna module can be designed in a one-stop manner! Introducing case studies for implementation in government agencies (radar)!

Here is an example of the "Front-End Module for Active Phased Array Radar" introduced to government agencies. Radar sites installed in various locations across Japan monitor and guard the area and surrounding airspace. In recent years, active phased array radars have become mainstream, aiming to improve responsiveness to low RCS targets such as projectiles. Tamagawa Electronics has a track record of introducing front-end modules that up/down convert frequencies in the RF band directly below the antenna and in the baseband IF band. [Case Overview] - Installation Site: Government Agencies (Radar) - Product Introduced: Front-End Module for Active Phased Array Radar *For more details, please refer to the related links or feel free to contact us.

Transformer Protection Often Overlooked in BCP Measures: Seismic Device for Transformers TTR

Transformer Protection Often Overlooked in BCP Measures: Seismic Device for Transformers TTR

Seismic measures start with "transformers"! We achieve efficient disaster reduction measures (damage mitigation and early recovery).

The "TTR type" is a seismic device for transformers that significantly reduces the displacement of transformer terminal sections caused by large seismic motions, preventing large-scale power outages due to transformer damage. With the installation of TTR, a displacement of ±50mm or less at the terminal section has been achieved for all experimental seismic waves. Based on the building's response characteristics, it is possible to calculate and simulate the displacement of the transformer during an earthquake. In past earthquakes (such as in Eastern Japan and Kumamoto), the heaviest transformers in the cubicle were damaged, resulting in many cases where even if emergency generators were intact, electricity could not be extracted. Transformers are not readily available, meaning that operations would be suspended during that time. The TTR not only protects the transformer but also enhances the overall rigidity of the cubicle, contributing to the protection of various relays and LCBs. It enables efficient disaster reduction measures (damage mitigation and early recovery). 【Features】 ■ Significantly suppresses displacement caused by seismic motion with a special absorber at the top of the transformer ■ Effective against continuous earthquakes ■ Can be installed within the cubicle ■ Minimal changes to panel size due to TTR installation ■ Does not compromise the effectiveness of the installed vibration-damping device *For more details, please refer to the PDF document or feel free to contact us.
