Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0029] The method for carrying out back-gold on the printed circuit board of the Ku-band microstrip type switch circuit provided by the present invention is to selectively carry out back-gold on the microwave printed circuit board, and will be positioned between the microstrip lines on both sides of the circuit element. The grounded base plate, that is, the back gold part of the printed circuit board, is isolated to suppress the coupling effect of the microwave signal, thereby improving the isolation of the microwave switch circuit.
[0030] This method that the present invention provides to the printed circuit board of the Ku-band microstrip type switch circuit is carried out back gold method, when carrying out back-gold ...
