From BC Systems comes Model RF40015, an RF power amplifier designed for defense applications, in which broadband frequency coverage of 20MHz to 305MHz and RF output power of at least 100W in Class AB operation is desired, in a compact, rugged package.

The Model RF40015 combines the latest GaN RF power transistors with the company's design and fabrication techniques to deliver high RF power density in a module measuring only 14cm x 11.4cm x 4.1cm and weighing less than 0.9kg. It has extremely fast blanking speed of less than 5s for excellent noise performance and low standby power consumption, as well as efficiency of at least 30 percent and the ability to deliver its full RF power output into VSWR of 2.5:1.

The amplifier incorporates a custom DC/DC converter designed and manufactured by BC Systems that is highly efficient and allows the amplifier to operate from a 26Vdc to 30Vdc power source. The unit is fully protected for over-current and over-voltage conditions, and has an operating temperature range of -20C to +85C (-45C to +95C non-operating). It can be specified with an integrated low-power sampling port for RF output monitoring as well as a directional coupler.

BC Systems can customize the DA Module to meet various military standards as well as for parameters such as operating frequency range, mounting configurations, and connector type.
