Radio frequency receiving and transmitting assembly for vehicle-mounted communication

The invention provides a radio frequency receiving and transmitting assembly for vehicle-mounted communication. The radio frequency receiving and transmitting assembly is characterized by comprising abox body, a box cover and a functional module. A first connector and a second connector are arranged on the box body. The functional module comprises a radio frequency part, a driving part and a receiving LNA amplification part. The radio frequency part, the driving part and the receiving LNA amplification part are separately arranged in the accommodating cavity. The radio frequency part comprises a first transceiving switch module, a first straight-through switch module, a transmitting power amplification module, a second straight-through switch module, a directional coupling module, a second transceiving switch module and a band-pass filtering module. The receiving LNA amplification part comprises a receiving LNA amplification module. The receiving and transmitting assembly is beneficial to reducing the size, m
