The mixer composed of analog multiplier MC1596 is shown in the figure.
This circuit
can
mix at high or very high frequencies . At - 200MHz
, the circuit has a mixing gain of 9dB and
a sensitivity of 14yv.
Compared with transistor mixers , its advantages are that
there are less combined frequency components in the output current and less interference; the requirements for the amplitude of the local oscillator voltage are not very strict, and there will be no serious distortion due to the small Ulm, and
the isolation Good performance, low frequency traction.
