Abstract
The present invention relates to a baseband transmitter using a precision voltage reference and field effect transistor switches in an arrangement such that output amplitude variations due to power supply and transistor 'on' voltage variations are virtually eliminated. The present invention results in a transmitter suitable for the generation of transmit signals conforming to different rate and/or frequency constraints. The data rate and output pulse characteristics of the transmitter are selected by a single 1-of-N switch selection. A common amplifier is provided for different data rates.
