ML12002
Analog Mixer
Legacy Device:
Motorola MC12002
The ML12002 is a double balanced analog mixer, includ-
ing an input amplifier feeding the mixer carrier port and a
temperature compensated bias regulator. The input circuits
for both the amplifier and mixer are differential amplifier
circuits. The on-chip regulator provides all of the required
biasing.
This circuit is designed for use as a balanced mixer in
high-frequency wide-band circuits. Other typical applica-
tions include suppressed carrier and amplitude modulation,
synchronous AM detection, FM detection, phase detection,
and frequency doubling, at frequencies up to UHF.
There are two package offerings:
• Plastic Dual Inline 14 Lead, P Dip.
• Plastic Surface Mount 14 Lead SOIC.
• Operating Temperature Range: TA = –30° to +85°C
