Sequoia Technology

For more than twenty five years Sequoia Technology has been one of the leading technical distributors of wireless components and products. Renowned for technical design competence and leading edge components, many customers rely on the software and hardware designs we offer, enabling considerably reduced time to market for their end products. In addition, the Sequoia group has, for some years, designed, developed and manufactured many of its own wireless products.

Many of the wireless components featured here are also used in our own designs, giving us a unique technical component experience to share with our customers. Whether you want technical expertise for the components you buy, or you would like us to design and manufacture for you – put us and our reputation to the test!
