Abstract

The invention provides a structure of a duplexer in a digital microwave outdoor unit; the structure is to set a platform next to the radio frequency transceiver module, and two square waveguide interfaces are symmetrically arranged on the platform, corresponding to the positions of the square waveguide interfaces, double The two square waveguide interfaces on the duplexer are connected to the waveguide interface, so that the duplexer is placed on the platform next to the RF transceiver module, and a radiator shell is covered on the duplexer, and it is fixed on the RF transceiver module with screws , a circular waveguide interface is provided on the heat sink shell, and is connected with the circular waveguide on the duplexer. The advantage of the present invention is that it is convenient to disassemble the duplexer, and the duplexer can be replaced only by disassembling the radiator shell above the duplexer. The cost of duplexer can be reduced to about 20% of the total price of ODU.

Description

Duplexer in digital microwave outdoor unit

技术领域technical field

本发明涉及一种数字微波通讯中，微波传输设备的结构。 The invention relates to a structure of microwave transmission equipment in digital microwave communication. the

背景技术Background technique

传统的数字微波室外单元(ODU)，是将双工器内置，即放置在ODU的最底层，由于双工器工作带宽较窄，为了应用于不同的工作波段，ODU需要更换不同性能要求的双工器，这样，需要拆卸ODU所有模块后，才能更换双工器，工程量大，而且容易损坏模块，更换一次双工器费用，约占ODU总价的40％。 The traditional digital microwave outdoor unit (ODU) has a built-in duplexer, that is, it is placed at the bottom of the ODU. Due to the narrow working bandwidth of the duplexer, in order to apply to different working bands, the ODU needs to be replaced with a duplexer with different performance requirements. In this way, it is necessary to disassemble all the modules of the ODU before replacing the duplexer, which requires a large amount of work and is easy to damage the modules. The cost of replacing a duplexer accounts for about 40% of the total price of the ODU. the
