After briefly reviewing the users' requirements and the results of traffic scenario simulations needed to size the system, the design of the European data relay system (DRS) (ground and space segment) is presented in detail. The interrelationship wit

A fully integrated monolithic power amplifier (PA) for DCS/PCS applications has been integrated in 0.25 /spl mu/m SiGe BiCMOS technology. The three-stages power amplifier delivers 31.8 dBm of output power (Pout) with 63% power added efficiency (PAE).

The demand for land-mobile communications on a Europe-wide basis is an important and pressing problem. The pan-European cellular network now in the planning stage will be slow in coming and it will have its limitations. A regional satellite system fo
