High-power front-end module for automotive V2V and V2X applications

17 December 2020

The new SKYA21043, a highly-integrated, 5 GHz front-end module (FEM) from Skyworks, incorporates a 5 GHz single-pole, double-throw transmit/receive switch, a 5 GHz high-gain low-noise amplifier (LNA) with bypass, and a 5 GHz power amplifier intended for high-power 802.11p applications and systems.

Qualified to AEC-Q104 (Grade 2), the SKYA21043 meets rugged reliability requirements for automotive Source: SkyworksSource: Skyworksapplications including vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) covering 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. 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.

The FEM is suited for a wide operating temperature range of -40° C to 105° C for high ambient temp rooftop antennas, and an integrated logarithmic power detector is included to provide closed-loop power control over 20 dB of dynamic range. The device is provided in a compact, 24 pin 3 mm x 5 mm conformally shielded land grid array package.
