Abstract(in English)	We propose a 1 - 30 MHz Software Defined Radio (SDR) with high-speed (100MHz) RF sampling. This receiver has a very high sensitivity (8dB NF), IP3 (+23dBm) and 130dB blocking Dynamic range (150Hz BW). This SDR has 2 receiving channels for wideband (1.25MHz to 10MHz) and narrowband (150Hz to 500kHz). There are no analog mixers, synthesizers and no analog AGC circuit on this receiver. We propose an appropriate NF calculation in the digital section in order to achieve very high sensitivity. We also propose a very high performance analog front-end in order to keep very high IP3 and IP2. Thereby, this SDR has been able to achieve high performance reception with narrowband filtering from 150 Hz to 500kHz at an oversampled rate of 100 MHz. This SDR also supports various demodulation types, such as DSB, USB, LSB, ISB, CW and Narrow FM.
