A complex-pole load is configured as a parallel circuit, having 4 transistors arranged in pairs. Each pair of transistors has a transistor gated by a control voltage sources, and connected in parallel with a transistor diode connected for gating by the respective input. The control voltage sources result in the circuit synthesizing a first order complex pole at a positive IF (+IF) or a negative IF (−IF) for channel selection and image rejection, offering image rejection and channel selection concurrently.
