#

Since 1974, Temwell Group has established itself as a leading Taiwan-based manufacturer specializing in 5G RF filter solutions for wireless communications. Our products are integral to a wide range of high-end markets, including aerospace, satellite communications, AIoT, 5G networking, Internet of Vehicles, drones, mining transmission, medical, military, laboratory, transportation, energy, and broadcasting (CATV).

TEMWELL Corporation has been a global expert in the design and production of RF Helical BandPass Filters since 1994, utilizing quarter-wavelength (λ/4) technology to develop comprehensive solutions across all frequency bands. With over 5,000 completed specification sheets available online, we demonstrate our extensive capabilities and commitment to innovation.

To meet the evolving needs of RF engineers and projects worldwide, our R&D team has expanded its focus to include a broad spectrum of 5G RF filters, such as Cavity Filters and SMD Dielectric Resonator (DR) Filters, supporting four fundamental filter types. We have also extended our RF technology through Temstron, enabling us to deliver complete RF solutions that are technologically advanced, cost-effective, and globally compliant.

For more than two decades, the TEMWELL brand has concentrated on the design and manufacture of various RF filters, including Helical, Cavity, LC, and SMD filters, available in highpass, lowpass, bandpass, and bandstop (notch) configurations. Our 5G RF filter expertise and dedicated R&D team are positioned to support your most demanding projects.

The Temstron brand complements our offering with both customized and standard 5G RF and microwave components, such as RF duplexers/diplexers, multiplexers, combiners, splitters, power dividers, attenuators, circulators, couplers, power amplifiers/LNAs, and solutions for obsolete coils and inductors. Our robust supply chain makes us a preferred source for 5G RF microwave components.
