摘要

Design and performance of a novel Direct Up-Conversion MMIC will be described. The circuit accepts analog differential or single-ended signals from a DA C, forms a sampling pulse from the DAC clock, and creates a time domain waveform that is a pulse doublet train amplitude modulated by the DA C input. The appropriate spectral line is then obtained via bandpass filtering. This approach minimizes cost, volume, power, and weight by eliminating the requirement for a Local Oscillator. The MMIC is implemented in a fully selective 0.15 um double recess PHEMT process.
