Available in PDF, EPUB and Kindle. Book excerpt: These results showed that it is feasible to implement low power 24-GHz communication devices with reasonable performance using a 130-nm CMOS technology. A fully integrated receiver is demonstrated. It consists of an RF front-end, IF amplifier, passive mixer, variable gain amplifier (VGA) and lower pass filter (LPF). It utilizes dual down conversion which requires one 21.3-GHz frequency synthesizer and a divide-by-8 circuit to generate the second local oscillator signal. A distributed transmitter/receiver switch is used to share the use of one on-chip antenna by the receiver and transmitter. A wireless communication link is demonstrated using fully integrated receiver and transmitter. A ~21.7-GHz single tone generated by the transmitter is successfully picked up and down-converted to baseband by the receiver which is 5m away from the transmitter. This demonstration is a great step toward the realization of a single chip radio.
