BC Systems RF PA for Defense Applications
Delivers 20 W from 25 to 1000 MHz
Compact BC Systems GaN-based Military RF Power Amplifier Produces 20 W from 25 to 1000 MHz
NY – March 17, 2010 – BC Systems today introduced the DA Module, an RF power amplifier for defense applications
such as manpack and man-portable communications and electronic warfare systems that combines optimum power
supply/RF power amplifier integration, a broad frequency range of 25 to 1000 MHz, and RF output power of at least
20 W in an enclosure measuring only 4.5 x 3 x 0.6 in. and weighing less than 1 lb.
The amplifier is based
on the latest Gallium Nitride (GaN) RF power transistors that combine high RF power density with broadband
frequency coverage. BC Systems designs and manufactures all of the power supplies for its RF power amplifiers,
which allows the amplifier to achieve the highest performance and reliability in the smallest footprint.
The amplifier is designed to be operated in Class AB mode, is unconditionally stable over all combinations of load
impedance and phase conditions, and can operate at full RF output power into a VSWR of 2.5:1. It has extremely
fast blanking speed of less than 5 µs to achieve excellent noise performance and low standby power consumption,
and efficiency is at least 30%. The DA Module’s custom DC-to-DC converter allows the amplifier to operate from a
22 to 34 VDC power source, and full protection is provided for over-current and over-voltage conditions. Operating
temperature range is -20 to +85 deg. C and non-operating temperature range is -45 to +95 deg. C. The amplifier can
be specified with an integrated low-power sampling port for RF output monitoring as well as an internal
The DA Module can be customized to meet various military standards as well as
customer-specified mounting, configuration, and performance parameters.
