Abstract(in English) | An ultimate software-defined radio might convert RF signals to digital signals by an analog-digital converter(ADC). Such ADC requires ultra high-resolution and ultra fast sampling rate because ordinary radios receive RF signals of from about -20dBm to -100dBm. It is unacceptable for portable wireless terminals. Therefore, analog devices such as low noise amplifiers, frequency converters, power amplifiers cannot be eliminated from those terminals. We review recent advantages in those vital RF devices, broadband LNAs, broadband mixers, and polar loop transmitters. We also mention three-dimensional MMIC technology, which makes highly integration and cost reduction of MMICs possible. |
