摘要

作者报道了一种用于六芯片连续检测对数放大器(SDLA)的GaAs单片微波集成电路(MMIC)，该电路工作在2至7 GHz的频带上，在54 dB动态范围内，记录误差在+或1.25 dB以内。这非常接近9db级增益的理论值+或1.1 dB。该结果代表了2ghz以上SDLA的混合MIC和MMIC实现的最佳公开数据和每级最低芯片数。给出了该模块在31℃下的实测性能总结

A GaAs MMIC for a 2-7 GHz successive detection logarithmic amplifier

The author reports on a GaAs monolithic microwave integrated circuit (MMIC) for a six-chip successive detection logarithmic amplifier (SDLA) which operates over the frequency band of 2 to 7 GHz with a logging error within +or-1.25 dB over a 54-dB dynamic range. This is very close to the theoretical value of +or-1.1 dB for a 9-dB stage gain. The results represent the best published figures and lowest chip count per stage for both hybrid MIC and MMIC realizations of an SDLA above 2 GHz. A summary of the measured performance of the module at 31 degrees C is given.<>
