[0031] Embodiment Five: Please refer to Figures 1-4 , based on Embodiment One, the present utility model provides a technical solution: The comb spectrum module 11 generates two path of dot frequency signals through a frequency selection filter. One path serves as the reference clock of the DDS, which is 1*00MHz, and the other path is the C-band dot frequency source required by the local oscillator unit, which is *.4GH. The output power of the 1*00MHz signal of the comb spectrum module 11 is about -12dBm. After power splitting and passing through two-stage frequency selection filters, the power is about -27dBm.
[0032] Analysis of the above content: According to the requirements of the technical agreement, the transceiver component uses a temperature-compensated and vibration-resistant crystal oscillator as the reference. In the solution, a 100M temperature-compensated and vibration-resistant crystal oscillator from Jiangsu Shangpin is selected as the reference benchmark, and its performance is as follows:
[0033] The start-up time of the crystal oscillator is less than 150ms, and the voltage regulator time is less than 10ms, which can meet the index requirement that the power-on amplitude stabilization time of the clock signal is less than 150ms.
[0034] The crystal oscillator signal is power-adjusted by an amplifier and then split into two paths. One path is power-adjusted through a π attenuation network and then low-pass filtered to provide the reference clock for the local oscillator unit, with a power of about 6dBm; the other path is split again by a power splitter. One path is power-adjusted by an amplifier and used as the reference clock for the FPGA of the power control unit, with a power of about 12dBm; one path is power-adjusted through a π attenuation network and used as the fundamental frequency clock for the comb spectrum module. In the comb spectrum module 11, an NPN-type triode from the 13th Research Institute of CETC is selected to amplify the input 100M fundamental frequency clock and provide a low-noise and power-stable signal for the subsequent step diodes. The noise figure of this device is about 2dB, and the gain is 18dB, which can meet the index requirements. The step diodes in the comb spectrum module 11 are mainly used for frequency doubling to generate a series of high-frequency components with a step of 100MHz. According to the design requirements, the fundamental frequency clock of the comb spectrum module 11 is 100M, and a signal of C-band *.4GHz needs to be generated. It is calculated that the step time Tt of the step diode should satisfy: Tt≤1 / Fn, that is, Tt≤278ps, and the carrier lifetime τ should satisfy τ≥1 / 2πF0, that is, τ≥1 / 2π*100MHz≈1.6ns. In the solution, a silicon step diode from Chengdu Yaguang is selected, which can meet the 100M clock requirement, and has a short step time and high frequency doubling efficiency.
[0035] Embodiment Six: Please refer to Figures 1-4 , based on Embodiment One, the present utility model provides a technical solution: The electrostatic discharge resistance of the power conversion module 5 and the power control module 13 is not less than 2000V.

The components should meet the grades specified in GJB548B-2005, and the anti-static ability of component parts should not be less than 2000V.
