AC coupled broadband ultrasonic preamplifier

AC coupled broadband ultrasonic preamplifier can provide very low noise amplification of ultrasonic signals from 20kHz to above 30MHz. It is specially designed for acoustic applications such as photoacoustic imaging and signal detection. PA series preamplifier is a very effective solution for those conventional applications that need high gain / low noise amplification for low amplitude ultrasonic signals.

The ultrasonic preamplifier is an instrument with solid shell, complete independence, simple operation and battery power supply. It provides the following characteristics: extremely low noise (the input in reference pa-2002 is 1.5uv peak to peak noise), input protection for high-voltage instantaneous input such as probe excitation pulse, and the ability to drive long coaxial cable. It can provide fixed gain and switch adjustable gain. When users need special gain or bandwidth, it can be provided according to special orders.
