| Abstract: | A bipolar electronic-controlled attenuator based on quadrature bridge which worked in short-wave band was designed, and a design of vector attenuator based on quadrature bridge is proposed Firstly the principle of the bipolar electronic-controlled attenuator based on quadrature bridge is analyzed. Then the quadrature bridge, PIN-diode-based electronic-controlled radio-frequency resistance and the linearity control circuit is designed. At last the principle of the vector attenuator based on quadrature bridge is analyzed. The results show that the attenuator range of the bipolar electronic-controlled attenuator can reach 30dB in short-wave band, and the function of linearity control basically achieved. |
