The O117SM3B is a GaAs reflective single-pole, double-throw switch with an operating frequency of DC~6GHz. The switch provides greater than 30dB isolation and less than 0.8dB insertion loss over the entire operating frequency range. It uses 0/+5V logic control and requires no external power supply bias and no power consumption. With excellent switching characteristics and port standing wave characteristics over the entire operating frequency range, it is ideally suited for microwave hybrid integrated circuits and multi-chip modules as well as low-power systems. The switch uses a 3x3mm surface-mount non-leaded ceramic package to achieve hermetic encapsulation. The surface of the pin pad is gold-plated and suitable for reflow soldering.
