A dual-band simultaneous receiving mixer with independent and linear gain control

A dual-band mixer that can receive multiple band signals simultaneously is reported. Using dual local oscillator (LO) signals simultaneously, the mixer achieves independent gain control through relative power control of the signals. Linear conversion gain control is also achieved through dual LO sig...

Description
Summary:A dual-band mixer that can receive multiple band signals simultaneously is reported. Using dual local oscillator (LO) signals simultaneously, the mixer achieves independent gain control through relative power control of the signals. Linear conversion gain control is also achieved through dual LO signal input with total LO power control. The new topology using two MOSFETs is adopted without the need for an additional LO power combiner. Test measurement results confirm that the mixer achieves independent and linear conversion gain control in dual-band simultaneous receiving. The new mixer has higher conversion gain than that of the previously reported single MOSFET mixer in the dual-band receiving.
