And lo, the Hittites did rise up out of their land (the Commonwealth of Massachusetts), and they did conquer Babylon...well, semiconductors, in any case. Hittite Microwave designs and develops microwave, millimeter-wave, and radio-frequency integrated circuits (RFICs) for aerospace, broadband, cellular, and military applications. In addition to standard amplifiers, frequency multipliers, mixers, modulators, switches, and other components, the company provides custom RFICs. It gets more than half of its sales from overseas customers. Boeing (about 14% of sales) is Hittite Microwave's top customer. Hittite Microwave was acquired by rival Analog Devices in 2014 in a deal valued at about $2 billion.
