摘要： A frequency conversion device, method, and system are described. The device includes a first intermediate frequency (IF) filter, a first local oscillator, an up frequency converter, and a first duplexer. The first IF filter is adapted to receive an IF signal, and send the IF signal after performing an IF filtering on the IF signal. The up frequency converter is adapted to receive the IF signal after the IF filtering and a local oscillator signal, perform an up frequency conversion on the IF signal to obtain a microwave signal according to the local oscillator signal, and send the microwave signal. The first duplexer is adapted to receive the microwave signal, and send the microwave signal after performing a band pass filtering on the microwave signal. By the use of the frequency conversion device, the frequency conversion of a digital microwave outdoor unit (ODU) once is thus realized.
