Amplifier Research - 350AH1A - 350 Watt CW, 10 Hz - 1 MHz amplifier (w/ DCP, IEEE-488, RS-232, USB and Ethernet interfaces )

More

The Model 350AH1A amplifier is a portable, self-contained, air-cooled, broadband, solid state amplifier unit designed for laboratory applications where instantaneous bandwidth, high gain and moderate power output are required. When used with an RF sweep generator, the 350AH1A will provide up to 350 watts of output power.

Housed in a stylish contemporary enclosure, the unit provides instantaneous power for typical applications such as magnetic susceptibility testing, 4–10 kHz requirement of CS114 of MIL-Std- 461F, antenna and component testing, watt-meter calibration and as a driver for higher power amplifiers. The 350AH1A is powered by a high efficiency switching supply, with auto ranging AC input circuitry which will automatically accept voltages from 90 to 260 VAC in the 47 to 63 Hz frequency range. The RF amplifier stages are protected from over-temperature and over-current conditions by removing the DC voltage to them when a fault is detected. The touch screen display on the front panel indicates the operational status and any pending fault conditions when an overtemperature, over-current or power supply fault has occurred. The unit can be returned to normal operation when the condition has been cleared. The unit also includes digital control for both local and remote control of the amplifier. The RISC microprocessor controller board provides IEEE-488 (GPIB), USB, Ethernet and asynchronous full duplex RS-232 communication control of all amplifier functions.

Two 350AH1A amplifiers may be used together in a “bridged” output configuration by supplying the same signal to both amplifiers and using the internal signal inversion feature of one amplifier. The amplifier output grounds are connected and the load is placed across the two amplifier outputs.

Amplifier Research

Founded in 1969, AR RF/Microwave Instrumentation is a world-class source for broadband high power, solid state, RF amplifiers and microwave amplifiers, TWT amplifiers, log periodic antennas and high-gain horn antennas, plus EMC test equipment, software and field probes and monitors.  AR RF/Microwave is a member of the AR family of companies that includes AR Modular RF, SunAR RF Motion and AR Europe; they are recognized around the globe for products that deliver both outstanding quality and exceptional value.

Throughout its 50 years (and counting), AR has been responsible for a number of “firsts” which have transformed not only EMC and RF testing but also the industries and equipment affected by these tests. A sampling of these innovations includes:

  • 10,000-watt tube amplifiers
  • 100-watt solid-state 100-1000 MHz instantaneous bandwidth Class A amplifier
  • First production 16,000-watt solid-state linear amplifier from 10 kHz to 225 MHz
  • 50,000-watt Class A power amplifier up to 225 MHz
  • 0.7 to 6 GHz high-power Class A & AB amplifier

Additionally, they push the limits of state-of-the-art design and have ruggedized their products to make them virtually indestructible. AR amplifiers are fully tested to the extreme to ensure customers receive a product that is built to last.
