Temp Variable Attenuators
|
These temperature variable attenuators are useful in negating temperature effects on amplifier circuits. In high frequency applications, amplifiers have a tendency to decrease their gain as the temperature rises. The temperature variable attenuator provides the opposite temperature characteristics than the amplifier as its attenuation decreases as the temperature rises. Using the temperature variable attenuator in series with the amplifier circuit will cancel out the temperature effects and result in a constant output over temperature. These attenuators can replace the Automatic Gain Control (AGC) components from the amplifier circuit resulting in reduced circuit size, reduced component count and ultimately reduced costs. |
