The need to translate frequencies up or down is a basic signal-chain need. The key component used to do this is the mixer, which essentially multiplies two signals together. In the frequency domain, ...

Direct conversion (or low IF) receiver designs have been in existence for many years. They are widely used in mobile phones and cordless telephones because of their simplicity and lower cost. However, ...

The following is excerpted from Chapter 8 of “RF Circuit Design, 2e” by Christopher Bowick. Moving up the scale in complexity, we come to the next evolutionary RF architecture: the ...

In high-speed wireless communications systems, signals must be translated in frequency by up-conversion or down-conversion for signal propagation and processing. Traditionally known as mixing, this ...

Radio frequency (RF) and wireless design are considered specialist skills within the electronics industry, so usually, only those involved understand the terminology and critical principles. However, ...

Linear Technology has launched a double-balanced mixer that can operate either as an up-converter or down-converter, with a very wide RF frequency range from 2GHz to 14GHz. The LTC5549 is able to ...
