Embodiment Construction
[0034] Please refer to the accompanying drawings for a further description of the present invention.
[0035] As shown in Figure 1, the double-channel single-sided fin line amplifying circuit board 1 has two parallel microstrip lines 102 on its front side, and a power amplifier chip 101 is arranged on the microstrip line 102; its back side is a double fin line 104, There are flying lead holes 103 on both sides of the microstrip line 102 . The power supply of the two power amplifier chips 101 is respectively on both sides of the microstrip line 102, one of which can be directly powered, and the other can not be directly powered because the power supply terminal is too close to the previous chip. One side of the flying wire method, place the bias circuit on a relatively empty position on the board, use the flying wire to pass through the flying wire hole 103 from the back of the circuit board 1 and solder it to the flying wire hole 103 on the front of the circuit board 1, and am...
