The SRFD3 RF Amplifier and Interface (SRFD3 Module) is the third phase in the development
of the Scaleable RF Driver (SRFD) subsystem. It is the first liquid cooled amplifier and lower
output power(10kW). The SRFD3 Module performs the following functions: Head/Body mode
switching, CAN communication link decoding, control and status communication between
the system and the RF amplifier, RF power amplification, and RF power sampling for power
monitoring by the Universal Power Monitor (UPM). The SRFD3 Module provides appropriate
test points, displays and adjustments to allow for calibration and troubleshooting in the field.
The SRFD3 Module will also incorporate water cooling for fan noise reduction.
The SRFD3 Module consists of five functional blocks: I/F Translation, Input Conditioning, RF
Amplifier, Output Conditioning and Input Power.
