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.
As a mixer, its balanced operation cancels out many unwanted mixing products, resulting in a "cleaner" output. It is a generalized case of an early circuit first used by Howard Jones in 1963, [ 2 ] invented independently and greatly augmented by Barrie Gilbert in 1967. [ 3 ]
The free design tool is the software accompaniment to ADI's complete portfolio of RF-to-digital functional blocks, allowing engineers to model RF signal chains using devices from across ADI's RF ...
The baseband processors [28] [29] and radio transceivers in all modern wireless networking devices and mobile phones are mass-produced using RF CMOS devices. [27] RF CMOS circuits are widely used to transmit and receive wireless signals in a variety of applications, such as satellite technology (such as GPS), Bluetooth, Wi-Fi, near-field ...
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 ...
DDS is used in applications such as signal generation, local oscillators in communication systems, function generators, mixers, modulators, [1] sound synthesizers and as part of a digital phase-locked loop. [2]
It uses a 16-bit 135MSPS analog-to-digital converter that provides performance over the range 0 to 55 MHz comparable to that of a conventional analog HF radio. The receiver will also operate in the VHF and UHF range using either mixer image or alias responses.
