• Subharmonic mixer — Whereas in a fundamental frequency mixer the output frequency (f {out}) contains the sum and difference of the fundamental tones of the two input signals (f {out}=f {1} f {2} or f {out}=f {1}+f {2}), in a subharmonic mixer the output signal is… …   Wikipedia

• Zero Intermediate Frequency — is a radio demodulation technique that does not use an intermediate frequency, but utilizes only one mixer stage to convert the desired signal directly to and from the baseband without any IF stages and without the need for external SAW filters …   Wikipedia

• High Shear Mixer — A high shear mixer disperses, or transports, one phase or ingredient (liquid, solid, gas) into a main continuous phase (liquid), with which it would normally be immiscible.Input of energyThis phase transport is accomplished by an input of energy …   Wikipedia

• Intermediate frequency — In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier frequency is shifted as an intermediate step in transmission or reception. The intermediate frequency is created by mixing the carrier… …   Wikipedia
