RF receiver design using the direct conversion approach at 5.8 GHz band based on IEEE 802.11a standard

This thesis presents the development and analysis of a radio frequency (RF) front-end direct conversion receiver at 5.725 – 5.825 GHz where IEEE 802.11a standard is used as performance test. The RF receiver is designed based on the commercialized products (off-the-shelf) where it focuses on the syst...
