Model IT2000 Series consists of switchable transformers for high power ultrasonic and RF transducer applications, as well as other laboratory applications requiring a broadband, high power, impedance matching system. These transformers are designed to provide DC isolation while passing RF power over the specified frequency range. The output impedances are based on a 50 ohm source and can be remotely selected via commands received from the Model 800A3. The IT2000 Series allows fast remote switching to accommodate broadband matching to various load impedances.
