| description | The utility model discloses a double-channel down-conversion switch control circuit. The circuit is equipped with a partial wave switching controlled external input signal and a partial wave switching control logic circuit. The partial wave switching control logic circuit has a partial wave switching control signal input end, a first polarized signal input end and a second polarized signal input end. The partial wave switching control logic circuit has four output ends, which are used for controlling a first high frequency amplifier, a second high frequency amplifier, a third high frequency amplifier and a fourth high frequency amplifier for partial wave switching respectively. When the partial wave switching controlled external input signal stays in a certain state, an RFin1 end of a double-channel down converter serves as an input end of a V partial wave, and an RFin2 end of the double-channel down converter serves as an input end of an H partial wave. When the external switching end stays in another state, the RFin1 end of the double-channel down converter serves as the input end of the H partial wave, and the RFin2 end of the double-channel down converter serves as the input end of the V partial wave. The double-channel down-conversion switch control circuit is suitable for high frequency heads with various structures such as an L-shaped structure and an I-shaped structure. Therefore, high frequency head structures can be designed more freely. |
