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 ...

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 ...

If you’ve ever used an RF signal analyzer, you’re probably used to seeing displays like the spectrum graph or constellation plot. Of course, trusting the answers you get from the instrument often ...

For RF inductor selection, José Martos and Heinz Zenkner stress the importance of evaluating inductance, natural resonant frequency, quality, DC resistance and rated current for high-frequency ...
