  2. Frequency mixer - Wikipedia

    en.wikipedia.org/wiki/Frequency_mixer

    Frequency mixer symbol. In electronics, a mixer, or frequency mixer, is an electrical circuit that creates new frequencies from two signals applied to it.In its most common application, two signals are applied to a mixer, and it produces new signals at the sum and difference of the original frequencies.

  3. Gilbert cell - Wikipedia

    en.wikipedia.org/wiki/Gilbert_cell

    Such circuits are widely used for frequency conversion in radio systems. [1] The advantage of this circuit is the output current is an accurate multiplication of the (differential) base currents of both inputs. As a mixer, its balanced operation cancels out many unwanted mixing products, resulting in a "cleaner" output.

    Circuit diagrams drawn with CircuiTikZ. CircuiTikZ is a TikZ add-on for drawing schematic diagrams. Advantages: Very professional looking output (same quality as in commercial textbooks). Active user community. Tikz can be used to draw almost anything, so it might be worth learning anyway. Disadvantages: Some learning of Tikz is required.

  5. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A drawing meant to depict the physical arrangement of the wires and the components they connect is called artwork or layout, physical design, or wiring diagram. Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment. In computer science, circuit ...

    en.wikipedia.org/wiki/Radio_transmitter_design

    A simple mixer will pass both of the input frequencies and all of their harmonics along with the sum and difference frequencies. If the simple mixer is replaced with a balanced mixer then the number of possible products is reduced. If the frequency mixer has fewer outputs the task of making sure that the final output is clean will be simpler.

  7. Electronic mixer - Wikipedia

    en.wikipedia.org/wiki/Electronic_mixer

    Additive mixers are also known as analog adders to distinguish from the related digital adder circuits. Simple additive mixers use Kirchhoff's circuit laws to add the currents of two or more signals together, and this terminology ("mixer") is only used in the realm of audio electronics where audio mixers are used to add together audio signals ...

  8. RF chain - Wikipedia

    en.wikipedia.org/wiki/RF_Chain

    An RF chain is a cascade of electronic components and sub-units which may include amplifiers, filters, mixers, attenuators and detectors. [1] It can take many forms, for example, as a wide-band receiver-detector for electronic warfare (EW) applications, as a tunable narrow-band receiver for communications purposes, as a repeater in signal distribution systems, or as an amplifier and up ...

    Block diagram of a superheterodyne receiver. The RF front end consists of the components on the left colored red. In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1]
