One of the hottest things in 2021 will be automotive applications involving vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) connectivity. To facilitate such applications, Skyworks Solutions has debuted its SKYA21043, a highly-integrated, 5-GHz front-end module (FEM) incorporating a 5-GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch; a 5-GHz high-gain, low-noise amplifier (LNA) with bypass; and a 5-GHz power amplifier (PA) intended for high-power 802.11p applications and systems.

V2V technology will provide our vehicles with tons of information about the speed and position of other vehicles; the net effect will be to alert drivers to potential dangers down the road and to mitigate accidents and traffic congestion. For its part, V2X encompasses both V2V and vehicle-to-infrastructure (V2I) technology; V2I is part of the U.S. Department of Transportation’s Intelligent Transportation Systems initiative that aims to develop better driver-assistance systems for smart parking and autonomous vehicles.

Qualified to AEC-Q104 (Grade 2), the SKYA21043 meets rugged reliability requirements for automotive applications including smart antennas, compensators, and roadside units for automotive infrastructure, backhaul and cellular small cells. The device boasts +29 dBm output power, making it one of the highest power solutions on the market today, Skyworks claims. Its compact, conformally shielded package size will reduce front-end board space by more than 50% and the product is supported by the automotive PPAP process.
