Abstract
A dual channel receiver (,) includes a front end bandpass filter (,) that has a front end bandwidth, a first mixer (,), a second mixer (,), and two essentially identical receiver back ends (,). The front end bandpass filter splits a received signal into a first signal (,) and a second signal (,) of essentially equal signal strengths and provides out of band isolation between first and second signal outputs (,). The first mixer is coupled to the first signal and to a high side injection signal (,), and generates a first mixer output signal (,). The second mixer is coupled to the second signal and to a low side injection signal (,), and generates a second mixer output signal (,). Each of the two essentially identical receiver back ends is coupled to one of the first and second mixer output signals.
