Normally Open SP11T-12T-18G 18GHz Coaxial Switch
| Leader-mw | Introduction to Normally Open SP11T-12T 18GHz Coaxial Switch |
The product in the picture is a coaxial switch with the part number LSP11T - 12T18Ghz. It is normally open and operates from DC to 18GHz.
This coaxial switch has several notable features. It offers low insertion loss, low voltage - standing - wave ratio (VSWR), and high isolation, which are crucial for maintaining signal integrity in RF applications. It is equipped with SMA connectors, which are widely used in microwave and RF systems for their reliable performance.
The switch can be controlled by a selectable TTL driver. The specification table shows that the insertion loss increases slightly as the frequency range goes up from DC to 18GHz. In terms of electrical characteristics, it can operate at different voltages (12V, 24V, 28V) with corresponding coil currents. The environmental specifications indicate a maximum switching time of 15ms and a mechanical life cycle of 2 million cycles, with a storage temperature range of - 55°C to 85°C.
