Abstract
According to the developing trend of modern HF communication,a circuit structure with high linearity and wide dynamic range for wideband receiver is proposed based on the state of engineering implementation tech-niques. The calculation of noise figure,determination of channel gain and actualization of dynamic range are an-alyzed . The method of parameters allocation and optimization of every part′s circuit are studied. Consideration in selecting devices is discussed. The way to improve dynamic range by means of Automatic Gain Control(AGC)is proposed. There are some innovations in the design of high linearity and high dynamic range. Test result indi-cates the device meets the design requirements.关键词
