示例性地,本公开实施例可适用于微波点对点通信设备,具体 用于6G~42G微波室外单元(ODU)产品。当IDU发射频率是350M时,开关7切换至MUX滤波器1,350M中频信号通过MUX滤波器1的350M发射通道进入开关8,此时开关8切换至MUX滤波器1,发射中频信号经过发射通道,通过微波双工器17发射到天线端。天线端接收到的微波信号,通过微波双工器17进入接收通道,将信号变频到140M中频,接收140M信号进入开关9,开关9选择MUX滤波器1,140M信号经过MUX滤波器1进入开关7,再通过N型接头11送给IDU。Illustratively, the embodiments of the present disclosure are applicable to microwave point-to-point communication equipment, and specifically to 6G-42G microwave outdoor unit (ODU) products. When the IDU transmission frequency is 350M, switch 7 is switched to MUX filter 1. The 350M intermediate frequency signal passes through the 350M transmission channel of MUX filter 1 and enters switch 8. At this time, switch 8 is switched to MUX filter 1, and the transmitted intermediate frequency signal passes through the transmission channel. , Transmitted to the antenna end through the microwave duplexer 17. The microwave signal received by the antenna end enters the receiving channel through the microwave duplexer 17, and the signal is converted to 140M intermediate frequency. The 140M signal is received and enters the switch 9, the switch 9 selects MUX filter 1, and the 140M signal passes through the MUX filter 1 and enters the switch 7. , And then sent to IDU through the N-type connector 11.
示例性地,当IDU发射频率是630M时,开关7切换至MUX滤波器2,630M中频信号通过MUX滤波器2的630M发射通道进入开关8,此时开关8切换至MUX滤波器2,发射中频信号经过发射通道,通过微波双工器17发射到天线端。天线端接收到的微波信号,通过微波双工器17进入接收通道,将信号变频到210M中频,接收210M信号进入开关9,开关9选择MUX滤波器2,210M信号经过MUX滤波器2进入开关7,再通过N型接头11送给IDU。Exemplarily, when the IDU transmission frequency is 630M, switch 7 is switched to MUX filter 2, and the 630M intermediate frequency signal enters the switch 8 through the 630M transmission channel of MUX filter 2. At this time, the switch 8 is switched to MUX filter 2, and the intermediate frequency is transmitted. The signal passes through the transmission channel and is transmitted to the antenna end through the microwave duplexer 17. The microwave signal received at the antenna end enters the receiving channel through the microwave duplexer 17, the signal is converted to an intermediate frequency of 210M, and the 210M signal is received and enters the switch 9, the switch 9 selects MUX filter 2, and the 210M signal passes through the MUX filter 2 and enters the switch 7. , And then sent to IDU through the N-type connector 11.
随着对ODU支持BW(bandwidth)=224M带宽的需求的提出,350M和140M的中频将无法满足BW=224M的要求。原因是系统对MUX滤波器1的350M发射和140M接收的收发抑制度有一定的要求,350M发射和140M接收的中频频率在BW=224M带宽时,收发信号频率有部分重叠,MUX滤波器无法达到收发抑制度的要求。因此350M和140M的中频支持的最大带宽是BW=112M,无法支持BW=240M的带宽需求。因此需要重新提出一组中频频率,在满足收发抑制度的要求下,能支持BW=224M带宽。As the requirement for ODU to support BW (bandwidth) = 224M bandwidth is proposed, the 350M and 140M IFs will not be able to meet the requirement of BW = 224M. The reason is that the system has certain requirements for MUX filter 1’s 350M transmission and 140M reception. When the IF frequency of 350M transmission and 140M reception is in the BW=224M bandwidth, the transmission and reception signal frequencies partially overlap, which cannot be achieved by the MUX filter. The requirements for receiving and sending suppression. Therefore, the maximum bandwidth supported by the 350M and 140M IF is BW=112M, which cannot support the bandwidth requirement of BW=240M. Therefore, it is necessary to re-propose a set of intermediate frequencies, which can support a bandwidth of BW=224M while meeting the requirements of transmission and reception suppression.
本公开实施例提出了一组新的中频频率,发射中频是630M,接收中频是210M。能满足BW=224M带宽的需求。解决了传统中频不能支持BW=224M带宽的问题。The embodiment of the present disclosure proposes a new set of intermediate frequency frequencies, the transmitting intermediate frequency is 630M, and the receiving intermediate frequency is 210M. It can meet the requirement of BW=224M bandwidth. It solves the problem that the traditional intermediate frequency cannot support the BW=224M bandwidth.
根据本公开实施例,可以在630M/210M和350M/140M两组中频之间自由选择,既兼顾了ODU能支持传统中频350M/140M旧版本的IDU,也能支持BW=224M大带宽的630M/210M新版本IDU。According to the embodiment of the present disclosure, it is possible to freely choose between 630M/210M and 350M/140M intermediate frequencies. It takes into account that the ODU can support the traditional intermediate frequency 350M/140M IDU of the old version, and it can also support the BW=224M large bandwidth 630M/ 210M new version IDU.
