Abstract

In the field of telecommunications, the applications for GaAs MMIC's beyond 2000 will include today's drivers such as Cellular and Portable Telephones, Direct Broadcast Systems and CATV distribution, but also the emerging markets of multimedia satellite communications, broadband Wireless Services, and high bit rate optical fibre systems. These latter systems use millimetre wave carrier frequencies, typically ranging from 10 GHz to 80 GHz. The full paper will look at the requirements which have shaped the Philips' GaAs technologies available today as well as what will be required for the future. Examples will be given of both the system requirement, circuit solution and the technology push.
