RF amplifier

Radiofrequency power amplifier that drives the transmit coil. Broadband, high-power, duty-cycle limited.

Why it matters to buyers: Arcing or low transmit power = stop scanning. Failures at high duty cycle announce themselves audibly.

Why it matters to engineers: Classed by fault codes — 30-series (power supply), 40-series (final stage). Final stage failure requires full RPA swap.
