The QuarterWave 9400 /6-18/40W is a four-channel RF amplifier delivering 40W output power across the 6–18 MHz band. Each channel operates independently with fixed ×50 gain, 400Vp-p output swing (±200V), and 50mA continuous current per channel. The amplifier combines high slew rate (400V/µs), low distortion (<0.1% THD from 10 Hz to 50 kHz), and fast transitions (<1µs) to support precision signal conditioning in measurement, communication, and test applications.
