UWB RF switch aids automotive connectivity
A 50-Ω SPDT RF switch from pSemi, the automotive-grade PE423211, covers bandwidths ranging from 300 MHz to 10.6 GHz. The part can be used in Bluetooth LE, ultra-wideband (UWB), ISM, and WLAN 802.11 a/b/g/n/ac/ax applications. Its suitability for BLE and UWB make the switch particularly useful for secure car access, telematics, sensing, infotainment, in-cabin monitoring systems, and general-purpose switching.
Qualified to AEC-Q100 Grade 2 requirements, the PE423211 operates over a temperature range of -40° to +105°C. The device combines low power, high isolation, and wide broadband frequency support in a compact 6-lead, 1.6×1.6-mm DFN package. It consumes less than 90 nA and provides ESD performance of 2000 V at HBM levels and 500 V at CDM levels.
The RF switch is manufactured on the company’s UltraCMOS process, a silicon-on-insulator technology. It also leverages HaRP technology enhancement, which reduces gate lag and insertion loss drift.
The PE423211 RF switch is sampling now, with production devices expected in late 2024. A datasheet for the switch was not available at the time of this announcement.
