BR-640A
MANUALLY CONTROLLED BROADBAND RF RECEIVER
The BR-640A is a modestly high gain broadband RF receiver specifically designed for use in ultrasonic systems. It features a bandwidth extending from 100 kHz to 50 MHz with an adjustable gain of -12 to 64 dB. It has a low noise figure with both high and low input impedances plus selectable high and low pass filters for bandwidth control. The BR-640A has fast recovery while still being protected against severe overload, allowing its use in a pulse echo (single transducer) type of operation.
