New Generating Systems are an Alternative for TWTAs

AR RF/Microwave Instrumentation has introduced a line of solid state field generating systems for many markets and applications.

These products offer an alternative to using traveling wave tube amplifiers (TWTAs) driving separate antennas. These antennas generate field strength up to 50 V/m. These performance characteristics were previously dominated by low MTBF and short warranty TWTAs. But the new solid-state designs offer better performance, increased reliability and a three-year warranty.

The amplifier and horn antenna combination forms one housed unit that can be tripod mounted. The AA series systems produce field strengths up to 50 V/m in two band-specific models over the 18 to 40 GHz frequency range. A separate rack-mounted unit (AA1000) contains the power supply and control circuitry (RF and DC cables included) for interfacing with these products. The rack-mounted assembly can be used for any of the AA series designs. AR can supply the AA model(s) and AA1000, in addition to a signal generator for a complete turnkey system. Standard products cover 18-26.5 GHz and 26.5-40 GHz frequency ranges.

Applications include EMC radiated susceptibility for MIL-STD-461 testing, radar systems, communications and TWTA replacements.
