ABSTRACT:
An electronic attenuator device is provided whose attenuation characteristics are substantially insensitive to variations in component element parameters and ambient temperature changes. Advantageously, an attenuator device made according to the present invention may be constructed at substantially reduced cost without loss of attenuation precision.
