摘要： Method and apparatus are provided for high linearity and low noise communication signal mixing. The apparatus includes a high linearity low noise mixer having an input stage coupled to a switch stage by a series-coupled blocking capacitance and input resistance. The input stage includes a buffer with negative feedback, and the switch stage includes a transistor based switch network connected to an amplifier that has feedback resistance and shunting capacitance. The method includes AC coupling an RF signal, increasing a gain of the RF signal, reducing third-order distortion by negatively feeding-back the RF signal, blocking IM2 generated from said gain increasing step, increasing a second-order input intercept point (IIP2) by attenuating the RF signal across a resistance, and applying a local oscillator input to the RF signal.

摘要： A dual-wire hybrid welding system includes a hybrid welding apparatus having laser, electric arc welder and second wire feeding device. Electric arc welder includes first wire feeding device for feeding first wire. Second wire feeding device is arranged and disposed to feed a second wire to electric arc welder. Laser and electric arc welder are arranged and disposed to direct energy toward at least two adjacent components along a joint and first wire is a consumable electrode fed into joint to establish molten pool generated by both laser and arc welder with first wire. Second wire is fed to molten pool to form a common molten pool. Common molten pool is operable to provide a full penetration weld with less total heat input to join the at least two adjacent components without cracking the components at a high constant weld speed.
