Skyworks unveils devices for motorway toll tag systems
Skyworks releases toll tag devices and ramps production to enable more than 40 million RF transponders
US analogue semiconductor manufacturer, Skyworks Solutions, has developed silicon mixer devices for low-noise receivers used in high-sensitivity radio frequency automotive motorway tag applications, including toll tag transponder systems.
The devices are being deployed across 40 million transponders supporting small signal RF applications where primary DC power is not available.
The SMS7630-079LF is a surface mountable, plastic packaged silicon mixer device designed for RF and microwave mixers and detectors.
The series includes low-barrier diodes and zero-bias detectors that combine Skyworks' advanced semiconductor technology with low-cost packaging techniques.
All solutions are 100 percent DC tested and deliver tight parameter distribution, which minimises performance variability. Wiring configurations include singles, common cathode, series pairs, unconnected pairs and dual-series pairs. They may be used for frequencies up to 10 gigahertz, given their low capacitance.
Skyworks' analogue devices are ideal for other RF mixer and power detection wireless applications including 802.11 wireless networking, CATV/Satcom, infrastructure, medical, military and test/measurement.
