The article examines digital radio frequency (RF) technology, which integrates digital and radio frequency systems into a single portable electronic device. In previous generations of wireless devices, digital and RF sections were usually subsections separated from each other. Their marriage has resulted in more flexible, agile RF transmitters and receivers capable of handling more complex RF signals. The technical benefit of digital RF is that it allows for more efficient use of the frequency spectrum and increased data throughput. These benefits help in the rapid deployment and acceptance of new technologies such as WLAN and Zigbee. But these advances have also brought complexity, resulting in often unpredictable design environments.
