A new, laboratory grade RF power amplifier that offers eight channels of low, CW power for simultaneous transmit and receive applications, and eight channels of high, peak-pulsed power for conventional MRI is presented. These FPGA controlled, multiple transmit channels can be matrix switched into 1, 2, 4, and 8 channel combinations for a range of 2W, 4W, 8W and 16W CW, and 2kW, 4kW, 8kW and 16kW peak power pulses. Further each channel can be used for independent phase, gain, frequency, space and time for maximum flexibility in RF field modulation. This power amplifier meets our wide ranging experimental requirements.
