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 (f0) and a special  
slash number to distinguish it from related units. The format of  
model numbers is as above where *** = f0.

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. Merrimac offers a wide range of Image Reject Mixers for numerous applications. All units are designed and built in accord with  
applicable specifications. Designers are invited to work closely with Merrimac engineers to insure best results.  
6. 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.
