SI2 Technologies


Founded in 2003 as a high-technology electronics company, SI2 is focused on the development and manufacture of custom RF and sensor systems primarily for the defense and aerospace markets. Examples of our products include conformal antennas and phased arrays which support multiple functions including communications, navigation, reconnaissance and radar for space, weight and power constrained applications. Other product areas range from microwave absorbers to wearable human performance sensors. In addition to conventional manufacturing approaches, SI2 utilizes proprietary Direct Write (digital printing) manufacturing technologies to produce FlexHybrid electronic systems and structures… basically how to take a “dumb” structure and make it “smart” by integrating an electronic capability such as a sensor or antenna system. Our facilities are located in Billerica, MA. For additional information, including how to contact us, please visit our website at
