Info as pdf-file

Description:

The NTE973D is a balanced modulator/demodulator in a 14-Lead DIP type package designed for use where the output voltage is a product of an input voltage (signal) and a switching function (carrier). Typical applications include suppressed carrier and amplitude modulation, synchronous dtetction, FM detection, phase detection, and chopper applications.

Features:

• Excellent Carrier Suppresion:
        56dB Typ @ 0.5MHz
        50dB Typ @ 10MHz
• Adjustable Gain and Signal Handling
• Balanced Inputs and Outputs

Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
