Abstract
An RF transmitter system operating on a broader frequency range and providing a higher output power dynamic range is described. Low power RF signal is produced from a baseband signal using a quadrature modulator and using a broadband local oscillator signal. A microcontroller system controls the RF transmitter by selecting frequency range to be produced by the frequency synthesizer, selecting appropriate amplification path for producing the required output power, controlling the power detection sections for providing precise automatic power and automatic gain control.
