RF Mixers
Tips & Advice to help you make your decision on RF Mixers
A radio frequency mixer (RF mixer) is an electronic circuit device consisting of three separate ports. Two of the ports are input ports, and the third is the output port. The two frequencies coming into the circuit via the input ports are mixed to produce a third frequency, which is the output. This mixing is usually done to either enhance a frequency, or to move a signal from one frequency to another.
The frequencies that enter an RF mixer are not simply added together to form a new frequency, they are actually both added and subtracted so that the output consists of two new frequencies. An example would be if one frequency input is 2 MHz and the second frequency input is 6 MHz. The output would be both 8 MHz (3 MHz + 6 MHz) and 4 MHz (6 MHz - 2 MHz).
There are a number of important specifications that one should take into account when evaluating the quality of an RF mixer. These include: input levels, conversion gain or loss, isolation, frequency range, impedance, and mixer type. Each of these individual elements need to be considered when ordering or designing circuit configurations for an RF mixer.

RF Mixers
Make signals clear and efficient with RF mixersBy Christine Pollock Radio frequency mixers (RF Mixers) make the signal process more efficient in equipment, because they convert radio frequency power from one source and match the radio frequency power of another source.
When looking for a RF mixer for your equipment, you should consider the radio frequency range, the local oscillator frequency range and power, the intermediate frequency range and the conversion loss. Also consider the configurations for your RF mixer, including:
1. Surface mount technology (SMT) in which low-frequency components mount to the top surface of a circuit board;
2. Through hole technology (THT), which is a package type similar to the SMT. THT is sturdier and a bit more complex, since pins hold the components together in the RF mixer before soldering;
3. And the flat pack, which is a printed-circuit-board surface-mount component package.
Buy RF mixers from a company specializing in RF and microwave products
