The CM-15N SR Passives series is a family of high isolation radio frequency (RF) passives (combiners, dividers, and couplers). They are designed to provide superior performance and reliability in extreme environments. The passives provide excellent intermodulation distortion (IMD) and maximum isolation. The robust construction and hermetically sealed package provide protection against extreme temperatures, moisture and corrosion. With an operating range of 698-2700 MHz, these passives are suitable for use in applications such as wireless infrastructure, high altitude or subsurface telecommunication systems, radar systems and other challenging applications. They also feature excellent insertion loss, return loss, and low VSWR.
