Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF) input. When the LO is ...

Custom MMIC has launched a series of IP3 fundamental mixers featuring overlapping RF/LO frequencies spanning 6 GHz to 26 GHz, with each model demonstrating low conversion loss high IP3, high isolation ...

Linear Technology introduced the LTC5549, a double-balanced mixer that can operate either as an upconverter or downconverter, with a very wide RF frequency range from 2GHz to 14GHz. The LTC5549 offers ...

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 ...

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 ...
