A high power density, design has allowed us to produce a dual-band series with power levels from 30 to 50 watts P1dB, 20 MHz to 6 GHz solid-state amplifier in either a compact 4U or 7U package. This amplifier series is not only ideal for RF immunity testing to standards such as ISO11452-9 but also many 5G infostructure component tests. The touch screen colour display gives an immediate visual indication of the operating status of the amplifier and access to diagnostic information such as gate current and heatsink temperature. The fan speed adjusts depending on the heatsink temperature thus ensuring the minimum audio noise level possible in the operating environment. The dual directional calibrated coupler provides a quick and easy way to monitor forward and reflected power with any power meter. Input overdrive protection prevents damage to the input devices due to accidental high input power. Multiple remote interfaces are available as standard including USB, GPIB, RS232, and Ethernet. Amplifier gain can be controlled either remotely through one of the available interfaces or via the front panel touch screen.
