| Abstract: | Pseudo-synchronous Digital Hierarchy （PDH） microwave outdoor units （ODU） , as the RF transceiver unit of PDH system, mainly realizes the frequency conversion and power conversion of the transceiver signal, and provides the transceiver channels for the system to send and receive the Intermediate Frequency（IF）. This paper expounds the frequency plan, working principle, overall design, specific technical indicators and the implementation of the system. |
