Abstract
A reconfigurable image suppressing receiver includes a front-end amplifier, a first multi-mode circuit, a second multi-mode circuit, a wideband combining transformer, and a controller. The front-end amplifier is configured to receive a radio frequency (RF) signal from an antenna and adjust a gain of the RF signal. The first multi-mode circuit is 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. The second multi-mode circuit is configured to mix a second instance of the RF signal with a quadrature local oscillator signal to generate a quadrature IF signal. The wideband combining transformer is configured to combine the in-phase IF signal and the quadrature IF signal to generate a combined IF signal. The controller is configured to adjust one or more tunable parameters associated with the combined IF signal.
