CBA 6G-120D

1.8 GHz to 6 GHz 120 Watt Single Band Power Amplifier

  • Compact Design
  • Touch Screen Color display
  • Input Overdrive Protection
  • USB, Ethernet, GPIB and RS232
  • Built in Calibrated Directional Coupler

New, high power density, design has allowed us to produce a 80 watt, 1.8 GHz to 6 GHz amplifier in a compact 4U package. With a minimum of 100 watts of linear power this amplifier is ideal for RF immunity testing in a GTEM Cell or with a wide range of available horn antenna such as the Teseq BHA range. Readily integrated with the Teseq ITS 6006 80 MHz to 6 GHz test system these amplifiers can form part of a broadband test system. The touch screen colour display gives an immediate visual indication of forward and reverse power along with the current operating status of the amplifier and access to diagnostic information such as gate current and heatsink temperature.
Fan speed adjusts depending on heatsink temperature thus ensuring the minimum audio noise level possible in the operating environment. The inbuilt calibrated forward power coupler provides a quick and easy way to monitor forward power with any power meter. Multiple remote interfaces are available as standard including USB, GPIB, RS232 and Ethernet. The amplifier is designed ready for a simple upgrade to higher power levels by the addition of extra power modules into the existing mainframe.
