Skyworks launches analog solutions for automotive toll tag systems

Skyworks Solutions Inc of Woburn, MA, USA (which manufactures high-reliability analog and mixed-signal semiconductors) has introduced analog solutions for low-noise receivers used in high-sensitivity radio frequency (RF) automotive highway tag applications, including toll tag transponder systems. The firm’s devices are being deployed across 40 million transponders supporting small-signal RF applications where primary DC power is not available.

“Electronic toll collection systems represent yet another application that leverages Skyworks’ wireless expertise to combine the benefits of RFID, microwave technology and satellite positioning to enable increased interoperability, particularly as cities and transportation agencies look to reduce costs, ease traffic congestion, improve safety and minimize environmental impacts,” says Liam K. Griffin, executive VP & general manager of high-performance analog.

Skyworks says that its solutions also suit other RF mixer and power detection wireless applications including 802.11 wireless networking, CATV/Satcom, infrastructure, medical, military and test/measurement.

In particular, 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’ semiconductor technology with low-cost packaging techniques. All solutions are 100% DC tested and deliver tight parameter distribution, minimizing performance variability. Wiring configurations include singles, common cathode, series pairs, unconnected pairs and dual-series pairs. Given their low capacitance, they may be used for frequencies up to 10GHz.
