Key Features

• Combines two independent groups of four IF signals

• Provides a front-panel port for signal monitoring

• Reports amplifier and power supply status locally and remotely

• Offers optional dual redundant amplifiers with OPT-R

The standard model uses a single-path amplifier. Specify OPT-R when ordering if redundant amplifiers are required. RF performance varies by connector configuration.
