Solid State Broadband High Power Amplifier
2170 – BBS4A6AUT
1000 - 3000 MHz / 1000 Watts
The BBS4A6AUT (SKU 2170) is suitable for octave bandwidth high power
CW, modulated, and pulse applications. This amplifier utilizes high power
GaN devices that provide wide frequency response, high gain, high peak
power capability, and low distortions. Exceptional performance, long-term
reliability and high efficiency are achieved by employing advanced
broadband RF matching networks and combining techniques, EMI/RFI
filters, and all qualified components. The amplifier is constructed within one
single 5RU drawer including the forced air-cooling. Standard operating
voltage is three phase 208 VAC line-to-line. Optional configuration is single
phase 180-260 VAC.
The amplifier includes a built in control and monitoring system, with protection functions which preserve high availability. Remote
management and diagnostics are via an embedded web server allowing network managed site status and control simply by
connecting the unit’s Ethernet port to a LAN. Using a web browser and the unit’s IP address (IPV4) allows ease of access with the
benefit of multi-level security. The control system core runs an embedded OS (Linux), has a built-in non-volatile memory for event
recording, and factory setup recovery features. The extended memory option allows storage of control parameters and event logs.
Empower RF’s ISO9001 Quality Assurance Program assures consistent performance and the highest reliability.
