RF Amplifiers Bias Controllers
-
RF amplifier bias controllers generate a regulated drain voltage and actively adjusts the gate voltage of an external amplifier to achieve constant bias current. It can be used to bias any enhancement and depletion type amplifier operating in Class-A regime with drain voltages (VDRAIN) as specified. These devices achieve excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures used to prevent RF performance degradation due to such variations.

300mA One-Channel Amplifiers
-
Piezo amplifiers/controllers are designed for high precision positioning of low-voltage piezo actuators. These amplifiers are tuned for extremely high output stability and extremely low signal noise at the output. A low amplifier signal-to-noise ratio is very important because it determines the total resolution of the actuator. The nearly unlimited resolution of piezo-electric actuators using these amplifiers results in ultra-precise movement.
