What is so special about these 1kW systems
Guaranteed 1 kW or 500 W RF performance over full bandwidth and temperature, which can be packaged in a 5U or 3U housing is not “typical” of product presently available in the market. Much larger rack sizes with power levels that are not sustained across an entire bandwidth and/or temperature range are what’s commonly available.
In addition to this, the user interface capabilities of this amplifier that are standard with Empower next generation designs allow the user to initiate remote management and diagnostics via an embedded web server, enabling 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 multilevel security. The control system core runs an embedded OS (Linux).
Event log and non-volatile memory
This allows for internal diagnostics and troubleshooting – basically, we have a flight recorder in the amplifier. In addition, the memory features enable us to record product and configuration information at time of manufacture.
Factory or user adjusted settings can be logged, as applicable.
Internal monitoring and protection features
Next generation amplifier family is designed to be actively (continuously) monitoring critical performance parameters – ie, temperature, current consumption, voltage levels, alarms, etc – and taking action via the microcontroller to initiate protection and/or shutdown to avoid PA damage.
Thermal management and reliability advantages
This is a “minimal touch” design which eliminates a number of manual process steps – design margin evaluation (DME) analysis and a full battery of qualification tests are integral to this product introduction. Detailed thermal simulations, heat spreading techniques, and device management all contribute to high reliability. Temperature compensation is actively running in these systems, including control down to the level of device quiescent current. Also, there is full monitoring and control of cooling fan speed and operation. When temperature is low, fan speed is reduced to prolong serviceability.
The BBS2E3KUT (SKU 2126) is suitable for octave bandwidth high power CW, modulated, and pulse applications. This amplifier utilizes high power LDMOS 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. The system comes standard to operate from 180-260VAC single phase or optionally can be ordered with a three phase AC supply.
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.
