Outline structure diagram
Note
Store in an environment with humidity less than 25%, pay attention to dust and static electricity prevention;
Good grounding, module ground, power ground, signal ground, equipment ground, and earth must be connected together;
Please pay attention to the power consumption of the product and consider the issue of amplifier heat dissipation during design;
The output signal cannot be left floating. Please connect it to a load, and ensure that the standing wave ratio (SWR) of the load is better than 5:1;
The input signal must not exceed 10dBm.
Please connect the attenuator to the module output before connecting it to the instrument. It is recommended to choose attenuators with frequencies ranging from 2 to 18GHz, attenuation values of 40dB, and attenuators above 30W.
Clean the surface of the product, do not soak the product in cleaning solution for cleaning.
