Model Numbering Note

*A complete model number shall be assigned upon

establishment of a full performance specification by the

factory in conjunction with the customer. The model

number shall include an indicator of the center frequency

related units. The format of model numbers is as above

General Notes:

1. Image Rejection Mixers are integrated networks composed of an in-phase power divider, two double

balanced mixers and two 90° quadrature hybrids. Their principal function is the separation of two signals

closely spaced in the frequency domain in, for example, a receiver’s IF stage.

2. An image is a spurious signal occurring in a receiver’s IF stage together with the real signal. Both

result from the mixing process. Normally, a passband filter selects the real signal while rejecting the

image. However, when the frequency difference between the real and image signals is relatively small,

conventional bandpass filters are generally inadequate.

3. In an Image Reject Mixer, the image is separated from the real signal by vector subtraction. The

resulting attenuation of the image is usually expressed as the ‘‘Image Rejection Ratio’’ in dB. (See

graph).

4. Several factors affect attainable image rejection. For example, image rejection is a function of

bandwidth, the phase and amplitude balances of the individual components chosen, mixer sensitivity

and VSWR interaction among other factors. The graph allows estimating attainable image rejection

under the variables of phase error and amplitude imbalance.

5. All Merrimac Image Reject Mixers comply with applicable sections of MIL-M-28837 and may be

supplied screened for compliance with additional specifications for military and space applications

requiring the highest reliability.
