CHAPTER Mixer Design
Figure 7.3 shows a one diode, single-ended mixer. This circuit is only found in very low-cost circuits, with the isolation between ports being supplied by bandpass and lowpass filters that are separated in frequency. Some of these single-ended mixer can also take advantage of a somewhat lower level of LO power needed to drive the single-

MT-080: Mixers and Modulators
An idealized mixer is shown in Figure 1. An RF (or IF) mixer (not to be confused with video and audio mixers) is an active or passive device that converts a signal from one frequency to another. It can either modulate or demodulate a signal. It has three signal connections, which are called ports in the language of radio engineers.
