Ultra-wide band differential input/output, high frequency active mixer in an integrated circuit

摘要

A wideband mixer (10) includes a core mixer (18) having input terminals and output terminals for, respectively, receiving differential input signals and providing amplified differential output signals. A steering module is coupled to the core mixer for receiving differential reference signals and providing bi-phase modulated amplified differential output signals. The core mixer (18) is configured to provide a value of gain between the differential input signals and the differential output signals. A bandwidth peaking network (14) is coupled to the core mixer and includes (a) a first coil and a first resistor connected in series and (b) a second coil and a second resistor connected in series. The first coil and resistor and the second coil and resistor, respectively, are coupled to the core mixer (18) for receiving the amplified differential output signals. The bandwidth peaking network is configured to increase the frequency bandwidth of the core mixer.
