High isolation switch brings adds to 5G automotive networks
For 5G automotive applications, Skyworks has introduced the SKY5A1007, a high isolation switch, which has been added to the company’s Sky5 product portfolio.
It has been designed to support the increasing demand for cellular vehicle-to-everything (C-V2X) connectivity. The SKY5A1007 CMOS, silicon-on-insulator (SoI) double-pole, double-throw (DPDT) switch has high-linearity performance, low insertion loss of 0.7dB typical at 5.75 to 5.925GHz and high isolation of 30dB at 3.8GHz, says Skyworks. It enables high speed switching between antennae for high data throughput and minimises the need for additional filtering. The SKY5A1007 meets the necessary requirements for 5G automotive telematics including operation within cellular, 5G new radio (NR) and operates over the 0.4 to 5.9GHz C-V2X bands, while supporting the wide temperature range needed for this emerging technology.
Switching is controlled by one voltage input. Depending on the logic voltage level applied to this pin, the Port1 and Port2 pins connect to one of the two other RF port pins (Port3 or Port4) through a low insertion loss path, while maintaining a high isolation path to the alternate port. No external DC blocking capacitors are required on the RF path as long as no DC voltage is applied externally, Skyworks advises.
Other features are support for automotive PPAP (Production Part Approval Process) and for IMDS (International Material Data System) declaration.
Operating temperature is the extended automotive range of -40 to +105 degrees C.
The SKY5A1007 double pole, double throw (DPDT) switch is provided in a compact, quad flat no-lead (QFN) package, measuring 1.83 x 1.83 x 0.5mm.
As well as automotive use, the SKY5A1007 can be used in cellular telematics and cellular compensator designs.
