ML12502

Analog Mixer With On–Chip

Regulator For Bias Control

Legacy Device: Motorola 12502

The ML12502 is the military temperature version of the

commercial ML12002 device. It is a double balanced ana-

log mixer, including an input amplifier feeding the mixer

carrier port and a temperature compensated bias regulator.

The input circuits for both the amplifier and mixer are dif-

ferential 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:

• Dual Inline 14 Lead, Ceramic Package.

• Operating Temperature Range: TA = –55° to +125°C
