摘要:An excitation reference source (Fc) is split through a 90 degree splitter. Oneoutput from the splitter is fed to the LO port of a mixer. Data is fed to the mixer's IF portand causes PRK modulation of the LO port's signal. The output of the mixer at the RFport is a PRK modulated quadrature signal. This is attenuated and added back onto thereference by a zero degree combiner ready for transmission to the transponder.
