AR Worldwide RF/Mcrowave Instrumentation has expanded its family of amplifiers with two new members. Designed for testing WiMAX components, models 15S5G7 and 30S5G7 offer 15 and 30 W in the 5 to 7 GHz range. Because the amplified signal is virtually indistinguishable from the signal generator’s output, these broadband amplifiers are suited for testing WiMAX components. Since the linearity of the amplifier signal is as good as the signal generator, there is no interference with adjacent channels. Its peak-to-peak power ratio delivers more useable power. Consequently, the performance of these broadband amplifiers allows them to be used as substitute transmitters.

The 15-W solid-state, self-contained, air-cooled 15S5G7 is designed for applications where instantaneous bandwidth and high gain are needed. It is protected from RF input overdrive. Its RF amplifiers stages are protected from overtemperature condition, which can occur due to cooling blockage or fan failure. There is a digital display on the front panel to indicate the status and fault conditions when an overtemperature or power supply fault has occurred.

The 15S5G7 includes digital control for both local and remote control of the amplifier. Its 8-bit RISC processor controlled board provides both IEEE-488 (GPIB) and asynchronous, full-duplex RS-232 control of all amplifier functions. Likewise, the 30 W 30S5G7 offers similar features.
