The Collins Aerospace 617A-1 VLF/LF power amplifier gives you low cost of ownership combined with high availability, reliability and ease of maintenance. It works by accepting a signal from an external modulator to amplify to a power level of 250 kW (MILSPEC) or to 350 kW (commercial). To achieve power levels of 2 MW, it uses a parallel connection of multiple amplifiers. It combines the output of 16 solid-state power amplifier modules and feeds the amplifier combining network for filtering and a 90 phase shift. In addition, it enables you to retrofit to antenna matching systems previously fed by a vacuum-tube transmitter and modulator-determined modes. You’ll also benefit from features such as automatic or manual tuning, high efficiency, graceful degradation and Built-In-Test.
