Design of a radio front-end module at 5 GHzIEEE 6th CAS Symp. on Emerging Technologies: Mobile and Wireless Comm. Shanghai, China, May 31-June 2,2004 Design of a Radio Front-end Module at 5 GHz Shaofang Gong, Magnus Karlsson and Adriana Serban Department of Technology and Natural Sciences, Linkoping University SE-601 74 Norrkoping, Sweden Abstract- A radio frequency (RF) front-end module at 5 GHz has been designed. The module consists of two switches, two 11. SPECIFICATION bandpass filters, a balun, a low noise amplifier (LNA) and a power amplifier (PA). The top-down design methodology is used in our design. Firstly, the module function is specified with input and output (I/O) ports. Secondly, the RF front-end is partitioned into functional blocks. High-level simulations can be done with block parameters. Thirdly, each block is……
