Bandwidth Radio Frequency Amplifier
The Bandwidth RF amplifier is a dedicated driver for acousto-optic devices, such as modulators and frequency shifters, operating within a specific frequency range and requiring less than 3 watts of power. It amplifies radio frequency (RF) signals to generate ultrasonic waves in the crystal of the device. The specific frequency and intensity of the amplified RF signal control the level of modulation, deflection, or tuning applied to the laser beam. The amplifier features efficient heat dissipation for reliable operation, and using a matched drive further enhances temperature stability for optimal performance.
