Claim Text:
1. A radiofrequency (RF) apparatus comprising: an RF signal input or output; a mixing module comprising a first plurality of Intermediate Frequency (IF) amplifiers, wherein at least one IF amplifier is coupled to the RF signal input or output via a first switch and a first plurality of input or output signals to or from the first plurality of IF amplifiers are not in quadrature; a multi-phase local oscillator signal generator configured to provide a reconfigurable switching signal phase to said first switch; and a vector conversion module configured to transmit or receive the first plurality of input or output signals and receive or provide a second plurality of input or output IF signals to or from a weighted sum of the first plurality of IF amplifier input or output signals, wherein at least one of the second plurality of the input or output IF signals is different from the first plurality of the IF amplifier input or output signals; and wherein the vector conversion module further comprises: a summing amplifier for at least one of the second plurality of input or output IF signals, the summing amplifier connected to at least one of the IF amplifiers via a weighted resistor network.
