V2X Module by NXP Semiconductors
TEF5100 Image

The TEF5100 from NXP Semiconductors is a V2X RF Transceiver that operates in the 760 MHz, 2.4 GHz, 5.4 GHz, 5.8 GHz, and 5.9 GHz frequency bands. It has an architecture based on direct conversion for both the transmitter and receiver, which eliminates expensive external filters. This automotive AECQ100 grade 2 transceiver has internal, digitally controlled gain stages at RF and baseband which provides the receiver with both a low noise figure and large dynamic range. The cut-off frequencies of the baseband filters are calibrated with an internal tuning loop and the filters support modulation bandwidths up to 20 MHz. It has independent fractional-N synthesizers that support dual channel operation. This transceiver has an internal auxiliary ADC for calibration purposes & to serve various external functions like power & temperature measurements.

The TEF5100 provides up to 33 dB of Tx gain, up to 78 dB of Rx gain, and has an Rx noise figure of 4.5 dB. It requires a DC supply from 1.2 to 3.3 V and can be controlled via a four-wire SPI interface. The transceiver has a high-speed parallel interface to support fast gain control, Rx/Tx switching and frequency hopping. It is ideal for use in 802.11 p, 802.11 a/b/g/n, and ARIB STD-T55/STD-T75 V2X communications applications.
