Modern RF amplifiers need both linearityand high efficiency. The linearity requirementis due to the use of modern modulationschemes, such as QAM (quadrature-amplitudemodulation) and OFDM ...

Overcoming the issues of DC offset in Direct Conversion for Software Defined Radios. Modulation is a process by which characteristics of a high-frequency carrier signal are altered to convey ...

Since the signal from the arbitrary waveform generator never changes in a test scenario, the demodulation process is not necessary as part of the EVM calculation. This eliminates a large percentage of ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

One of the best known of SDR suppliers to both military and civilian customers is the RF Communications Division of Harris Corporation. Harris, selected by the DoD's JTRS Joint Program Office for the ...
