Abstract: A single-ended mixer having a mismatched, high termination impedance is disclosed. The termination impedance can be mismatched by at least one order of magnitude higher than the standard impedance of a given design environment, such as a 50 Ohm environment for a radio frequency (RF) circuit. The termination impedance can be provided in close physical proximity to the mixer core of the single-ended mixer to allow a suitable bandwidth of operation.
