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 ...
New IQ Mixers can be configured as Image Reject Mixers or as Single-Sideband Upconverters IRVINE, Calif., April 11, 2017 /PRNewswire/ -- Pasternack, a leading provider of RF, microwave and millimeter ...
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 ...
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 project aims to build a simple and easily-reproducible RF/Microwave frequency counter that is based around a PIC16F876A microcontroller. This particular frequency counter has three inputs ...
Many engineers who use spectrum analyzers on a regular basis might be content to know that their instruments will produce a display of “power versus frequency” with little idea of what’s going on ...
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, ...
