System and Hardware Design Considerations for Mobile Phones-Sets

As cellular phone usage increases, solutions which not only meet the exact specifications, but are also economical in size, weight, and power dissipation must be found. This paper presents one such solution using a six chip set designed to meet the AMPS and TACS specifications. System requirements, architecture, as well as board level considerations and layout are discussed. In addition, the effects of shielding are presented along with test results.
