Abstract

The invention provides a general type 12.7-13.4 GHz full outdoor broadband IP digital microwave radio frequency unit. The radio frequency unit comprises radio frequency transmitting units and radio frequency receiving units. The total length of the radio frequency unit is smaller than or equal to 173 mm, and the total width of the radio frequency unit is smaller than or equal to 142 mm. The radio frequency transmitting units and the radio frequency receiving units are arranged in a plurality of independent cavities respectively. The adjacent cavities are communicated through grooves. Each radio frequency transmitting unit comprises a base band modulation circuit, a high and low station switching controller, a frequency mixer, a high-power amplifier, a medium frequency voltage-controlled oscillator, a radio frequency voltage-controlled oscillator and a loopback circuit. Each radio frequency receiving unit comprises a low-noise image rejection mixer, a base band amplifying circuit and a base band filter. The radio frequency unit is simple in structure, large in bandwidth, low in cost and high in generality, and the electromagnetic interference resisting ability of the circuits is high.
