RF Products

Semelab Ltd offers one of the world's broadest ranges of high performance RF Power MOSFETs.

Our devices are based on five unique die types, including products rated from 750mW to over 400W, at operating frequencies of up to 1GHz. The devices have an operating voltage of 12.5V, 28V and 50V.

We offer over 90 devices in a complete range of packages - to suit all applications, from low cost to ultra high spec, ultra high reliability systems.

Our unique Silicon Vertical DMOS process uses gold metalisation for maximum performance and reliability at high power.
