[Description]

The Bruker BioSpin BLAH300 is a high-power broadband linear RF amplifier designed for high-field nuclear magnetic resonance (NMR) spectroscopy systems. Operating across a specified frequency range of 650–900 MHz, the amplifier provides two selectable RF power outputs: a 300-watt peak output for solid-state NMR applications and a 50-watt peak output for high-resolution spectroscopy. Its Class AB architecture utilizes N-channel RF power MOSFET technology to deliver controlled radio-frequency pulses with a maximum full-power pulse width of 100 milliseconds and a 10% duty cycle. The amplifier incorporates protection against excessive output power, reflected RF power, overheating, and pulse timing limits. Additional features include RS485 serial communication, TTL-controlled RF blanking, an integrated power supply, and a 19-inch 3U rackmount enclosure for integration into compatible Bruker NMR spectrometer systems.
