Image Reject Mixers

 

 

In an image reject mixer (IRM) the image is separate from the real signal by vector subtraction. An image is a spurious signal occurring in a receiver's IF terminal together with the real signal. If the frequency difference between the image and the real signals is relatively small, a conventional bandpass filter is not adequate. An IRM consists of a Quadrature IF mixer and an IF hybrid. An image reject mixer can be used also to separate one of the two sidebands produced by the mixer. The IF hybrid combines the two IF outputs from the quadrature IF mixer to produce an IF version of either the upper or lower sideband of the input RF signal. The other sideband is rejected.

Products & Services
RF mixers convert RF power at one frequency into power at another frequency to make signal processing easier and more efficient. Search by Specification | Learn more about RF Mixers
RF phase detectors and comparators are circuits or instruments that provide a DC output voltage proportional to the difference in phase between two RF signals. Search by Specification | Learn more about RF Phase Detectors and Comparators
Static or motionless mixers are fins, obstructions, or channels mounted in pipes, designed to promote mixing as fluid flows through the mixer. Search by Specification | Learn more about Static Mixers
Low light cameras are designed for low light applications. They contain sensors that are highly sensitive to light and reduce images to a series of lines. Search by Specification | Learn more about Low Light Cameras
Audio mixers and audio consoles are units that combine signals from microphones and/or line level sources to produce a combined signal or signals. Learn more about Audio Mixers and Consoles
