• Communications
• Radar
• EMC / Radiated Immunity
• RF Component Testing

PRODUCT SELECTION

Performance Illustration

AGC mode enables internal feedback to automatically fix the gain to the level you set so the amplifier gain remains flat across the broadband range of the amplifier. This mode simplifies your system design or test setup with benefits including:

• Input signal equalization for compensating gain variations no longer required
• Treat the amplifier as a calibrated gain block within your test equipment chain or system design
• Eliminate the need for external system measurements: couplers, power sensors,meter, and system software feedback loops
• Ideal for fast and accurate test setup and execution

MGC is the output power mode found in your typical high power RF amplifier. The amp is run in an open loop mode where the output power vs frequency changes due to device non linearities and variations of temperature. With this mode you can take advantage of the gain peaks to get the most output power available if your working in the associated frequency range.

ALC mode allows the user to command the amplifier output to a specified power level rather than adjusting the exciter to a certain power level to achieve the desired output. The output power is set either through the front panel or as a SCPI command via the LAN port . Wouldn’t you rather command the amplifier to your desired output power rather than build your own feedback loop to control the exciter?

• Allows you to build your own system with uncalibrated components
• Eliminate the need to develop your own real-time feedback loop to monitor the output and set the input exciter level
• Simplifies and speeds up system integration
• Output Level is set accurately across the entire band

User Output Power Control (Selectable)

• Automatic Gain Control (AGC) - Utilizes internal feedback for flat gain output across the band
• Automatic Level Control (ALC) - when input signal varies, maintains user defined output without clipping
• Manual Gain Control (MGC) - user controls gain manually, runs like your typical amplifier in open loop

Measurement Modes (Selectable)

• The amplier reads the proper power level for your modulation type
• CW, CE (constant envelope modulation), FM, AM
• Digital Modulation- user inputs PAR (peak to average ratio)
• Multi-carrier / Multi-tone – up to 16 tones
• Pulse Modulation

Protection

• Load VSWR 3:1 (6:1 at 1/2 Psat)
• Input Overdrive Protection
• Thermal Overload Protection
• Over/Under AC voltage protection
• Out of Band Drive Protection

Built in Peak Detectors

• Input and Output Detectors
• Selectable Peak and RMS

You buy only the power you need today and add power amplifier blocks later when your requirements grow.
Adding 3U power amplifier blocks is accomplished easily and simply with no phase matching required Benefits of Scalability.

• Planning for an uncertain future, add a second when your future need requires more power
• Reduce overall capital expense
• Shorten project schedules
• Increase your amplifier utilization
• Support multiple projects simultaneously with individual units or combine units for large power requirements
