Reconfigurable wideband image suppressing receiver

A reconfigurable image suppressing receiver, comprising:

• a front-end amplifier configured to receive a radio frequency (RF) signal from an antenna and adjust a gain of the RF signal;
• a first multi-mode circuit configured to mix a first instance of the RF signal with an in-phase local oscillator signal to generate an in-phase intermediate frequency (IF) signal;
• a second multi-mode circuit configured to mix a second instance of the RF signal with a quadrature local oscillator signal to generate a quadrature IF signal;
• a wideband combining transformer configured to combine the in-phase IF signal and the quadrature IF signal to generate a combined IF signal;
• and
• a controller configured to adjust one or more tunable parameters associated with the combined IF signal, wherein the controller is configured to select a sideband or both sidebands of the reconfigurable image suppressing receiver by controlling at least one of a phase parameter of the in-phase and quadrature local oscillator signals or an amplitude parameter of the in-phase and quadrature IF signals,
• wherein the first multi-mode circuit is further configured to adjust a first phase of the in-phase local oscillator signal, and the second multi-mode circuit is further configured to adjust a second phase of the quadrature local oscillator signal,
• wherein the controller is configured to select the sideband of the reconfigurable image suppressing receiver by causing the first multi-mode circuit and the second multi-mode circuit to place the in-phase local oscillator signal and the quadrature local oscillator signal ±90 degrees out of phase when the first instance of the RF signal and the second instance of the RF signal are 0 or 180 degrees out of phase.
