Abstract: A wireless communication device for a vehicle comprises an antenna, a transceiver for processing a radio frequency (RF) signal, and an RF module placed between the antenna and the transceiver. The RF module comprises an attenuator and an antenna switch connected to the antenna. The antenna switch comprises a bypass path connected to the attenuator and providing a minimum power output when power is set to a minimum value.
