Empower RF Systems Intros 20 to 520 MHz High Power Amplifier Module
|
June 14, 2012 Press Release
Empower model BBM2E3KLP (SKU 1163) is a 20 to 520 MHz amplifier which is guaranteed to deliver 125W output
power and related RF performance under all specified temperature and environmental conditions. The amplifier
module is 7.0” x 4.0” x 1.5” and will be on display at upcoming tradeshows. This amplifier is suitable for
broadband jamming and high power linear applications in the UHF / VHF bands. This module utilizes high power LDMOS
transistors and also features built in control and monitoring, with protection functions. The control system core
has a built–in non-volatile memory for event recording and factory setup recovery features.
 What’s
so special about this module?
RF performance which is guaranteed over full bandwidth, temperature, and
environmental conditions is not “typical” of product presently available in the market.
In addition to
this, the user interface capabilities of this module and embedded controls that are standard with Empower next
generation designs allow the user to communicate with the PA building block with a PC or systems controller via
RS485. Analog control capabilities still exist, if applicable.
About an event log and non-volatile
memory
This allows for internal diagnostics and troubleshooting in a systems failure scenario –
basically, we have a flight recorder in the module which is continuously sampling and logging PA “health”. The
memory features also enable us to record product and configuration information at time of manufacture.
Internal monitoring and protection features
The module 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 this module,
including control of device level quiescent current.
User interface capabilities - the customer can
actually adjust some of the amplifier parameters through the RS485 connection
The user can adjust the gain
of the module, enable / disable the PA, and set the communication address. The user can also monitor current
consumption, internal temperature, supply voltage, and warning and error status related to system health.
Also, this product has legacy, analog control capabilities (voltage) for gain and enable / disable and analog
reporting for current and temperature.
Protection features
The PA has multiple defense
mechanisms which are active at the same time:- Current monitoring for the overall PA, the driver stages, and
the output devices. The over current protection (limiting) feature lowers output power.
- Temperature monitoring provides internal readings and lowers output power in an over temp condition, enables
with low gain for “warm up” in under temp condition.
- Voltage monitoring on the DC supply - PA shutdown or muting will result if triggered.
- Reverse polarity and ESD protection on the I/O lines – hardwired with 17 pin connector.
How
does this product compare to other commercially available products?
Our intention with this product is
to eliminate the guess work and “specs-manship” routinely found with PA modules in the market. Specs are
guaranteed across full bandwidth and over temperature - embedded controls and user access that is standard with
Empower next generation designs insures that there is no mystery about component performance or end use condition
if a system failure occurs.
Empower RF Systems is a leader in power amplifier solutions for defense,
commercial, and industrial applications. Our products incorporate the latest semiconductor and power combining
technologies and originate from an extensive library of “building block” designs. Solutions range from basic PA
modules to multifunction PA assemblies with embedded, microprocessor controllers.
