Due to the discontinuation in supply of a number of GaAs transistors, we will phase out the manufacture of certain power amplifier types during the course of 2015/16. The product ranges effected will be AM8X types operating in the frequency range 1-3GHz, and these will be removed from our web pages and online search database during this time.  Existing users will be supported for an extended period until such time as our component stocks are exhausted, estimated to be in excess of 2 years. Alternative models employing GaN technology are already available.
