What is the difference between a double balanced mixer and a double balanced modulator? Can they be used interchangable ?? If yes, why are they sold underseperate names ??

RE: Clarity on technical terms
A double balanced modulator is just a double balanced mixer applied as a modulator. A classic example is the Motorola MC1496. It is listed as a balanced modulator/demodulator. But, if you look at the simplified schematic, you will see that it is actually a double balanced mixer. Page 9 of the datasheet talks about using it as a double balanced mixer.
Why the confusion? Why are they sold under different names? Who knows... Probably a marketing rather than an engineering decision.
