This article briefly describes the working principle of the X531 true log amp circuit. Describe the simulation and experiment results of X531. According to the experimental exploration and the working principle of the circuit, the X531 unit circuit is optimized and the gain of the X531 integrated circuit unit is increased by about 30%. This article will provide the complete unit circuit of the X531 integrated circuit device before and after the improvement, and a comparison of the performance of the X531 integrated circuit before and after the improvement is listed. The X531 product’s phase shift frequency characteristic curve and input amplitude variation at -30dBmW input amplitude are listed Phase shift test data, but also gives the X531 six unit circuit cascade test results.
