- Clarifications about up and down converting mixers
In order to get either an up-converter, or a down-converter, you just filter out the signal that you don't want after the mixer Let's say that you wan't to down-convert, well just add a low pass filter after your mixer, and you are only going to get the difference of the frequencies
- The Basics of Mixers | DigiKey
The three ports (Figure 2) are referred to as the RF input port, LO (local oscillator) input port, and the IF (intermediate frequency) output port A mixer is also known as a downconverter if the mixer is part of a receiver or as an upconverter if it is part of a transmitter
- MT-080: Mixers and Modulators - Analog
When the sum frequency is used as the IF, the mixer called an upconverter; when the difference is used, the mixer is called a downconverter The former is often used in a transmit channel, the latter in a receive channel
- Application Note AN-200601 - Cross Technologies
The 2005 series uses BCD switches to adjust the frequency of the internal local oscillator This is a good solution in cases where the frequency needs to be changed only occasionally
- Radio Design 101 Episode 5 – RF Mixers and Frequency Conversion
episode focuses on RF mixers, and on frequency conversion schemes commonly used in wireless hardware with the basics, the process of up and down conversion is described and then demonstrated using a TinySA spectrum analyzer and a homebrew mixer built from an NE602 integrated circuit
- Intermediate Frequency (IF) Calculator and Formula
Calculate intermediate frequency (IF) with our calculator and learn about its formula, definition, and benefits in RF transceivers and heterodyne architectures
- High-Frequency Upconversion and Downconversion: A New RF Mixer from . . .
A standard mixer application is translating a signal between the RF frequency and the IF frequency (you were warned!) In both cases one of the input signals is the local oscillator (LO)
- Signal Chain Discussion Series: Mixers, Upconverters, and . . .
A local oscillator (LO) signal is sent to one port of the mixer, in some cases the LO signal is tunable to create a tunable frequency translation stage, and either the RF or IF port is the input output port depending on if upconversion or downconversion is being performed
