In order to make the high-frequency high-speed high-power transceiver component Transmitter and Receiver(T/R) work reliably and stably in complex electromagnetic environment, the design of component switching control, component power supply and ground, component layout and shielding are analyzed, the points of attention are suggested, and the design method is put forward. In the T/R component switching control design, the common mode interference problem is solved by a pair of delay and conjugate delay circuits to ensure that the transceiver time is longer than the driving switching time. The differential mode interference problem is solved by pulse width detection and maximum switching speed constraint. In the analysis of power supply and ground, the ground spacing is emphasized to not exceed one-twentieth of the signal wavelength. In the design of layout and shielding, the cavity resonance wavelength is analyzed in emphasis. Example modules are given and the above three design points are analyzed against each other to finally achieve stable and reliable operation in complex electromagnetic environments.
