The Series ACM Integrated Microwave Assemblies (IMAs) were developed for use in high performance Simulator and ATE Systems. They provide precise control of signal Amplitude and Pulse Modulation over a high dynamic range with very fine resolution and can cover a Frequency Range of 0.5 to 40 GHz in only three modules. These IMAs were designed using the optimum construction technology to achieve superior products and ease of manufacturing. These include Surface Mount Technology for the 0.5 to 2 GHz module, Chip & Wire (MIC) technology for the broad band 2 to 18 GHz module and Integrated Discrete Components for the much lower volume 18 to 40 GHz module.
