diode mixer

diode mixer

[′dī‚ōd ‚mik·sər]
(electronics)
A mixer that uses a crystal or electron tube diode; it is generally small enough to fit directly into a radio-frequency transmission line.

Among the topics are the origins of electronic mixers, semiconductor modeling, diode mixer theory, bipolar junction transistor theory and applications, and passive and active field effect transistor applications.
The signal reflected from the tuning fork is delected in the diode mixer and subsequently filtered to yield only the difference frequency, similar to what happens for the signal returned from the moving target vehicle (see Sec.
As we did for the tuning fork (which is a case describing phase modulation), we use the approximation to the diode equation response to find that the frequencies of the signal output from the diode mixer and filter are at [+ or -][f.
The value of [delta]f in current DTR radars is computed from the periodic sampling of the difference frequency output from the diode mixer.
