Description and Application


The Microwave Ablation Generator/Amplifier (MAGA) is a multi-carrier, multi-band generator/amplifier designed for use in a microwave surgical ablation system. The MAGA is a dual-band signal generator/amplifier which provides an L-Band (915 MHz +15 MHz) or S-Band (2450 MHz +50 MHz) RF output. It utilizes highly efficient, GaN transistor technology to provide an RF output signal with a user-selectable power level from 1W to 100W, in 1W steps.

The MAGA can be configured to generate signals internally (generator mode) or it can be configured to be driven by an external signal source (amplifier mode). When operated in generator mode, the system can be configured to generate a continuous wave (CW) or pulse waveform and supports a single carrier or multi-carrier operation. The MAGA is fully protected against input and output overdrive and has a very robust VSWR protection allowing up to a 100% reflection on the output.

The control functions are performed by an embedded microprocessor, based on the iMX6 processor. The microprocessor provides overall system monitoring and control as well as all external communication interfaces. Web GUI, RS422/485 and front panel interfaces are all supported.
