Abstract
GSM is currently the most widely adopted
digital cellular telephony standard in the
world. This paper presents details of the
design of the RF to baseband section of a
PCS1900 cellular handset. Detailed block
diagrams, circuit descriptions and measured
performance are presented. The radio has been
designed to operate with a baseband
Evaluation Board (EVB) and the performance
of the radio functioning in conjunction with
the baseband, as a complete handset, is
presented. A casework design for the handset
mechanics has also been developed; it includes
an integral patch antenna and allows complete
z-axis assembly to facilitate volume
manufacture
