The article discusses the applications of the developments of single-chip components in the RS-232 link. The conversion of previously complex mixed-signal circuits into single-chip components provides new opportunities and features for both new designs and upgrades to existing designs. One such class of devices that's beginning to appear in the marketplace is 2.4-GHz high-frequency, single-chip RF transceivers. Transceivers operating at 2.4 GHz offer advanced modulation schemes such as spread spectrum and allow the use of compact "printed circuit" antennas or surface- mount chip antennas, eliminating many of the problems associated with its lower-frequency ancestors.
