Amplifier Research 250W1000B

AR-250W1000B 250Watt, CW 80MHz-1000MHz RF Power Amplifier

The AR-250W1000B is a portable, self contained, air-cooled, broadband,
completely solid-state amplifier designed for applications where instantaneous
bandwidth, high gain and linearity are required. Push-pull circuitry is
utilized in all high power stages in the interest of lowering distortion and
improving stability.

The AR-250W1000B, when used with a sweep generator, will provide a minimum of
250 watts of RF power.
The AR-250W1000B is equipped with a Digital Control Panel (DCP) which provides
both local and remote control of the amplifier. The DCP uses a color LCD touch
screen and a single rotary knob to offer status reporting and control
capability. The display provides operational presentation of Forward Power and
Reflected Power plus amplifier status. Special features include a gain
control, internal automatic level control (ALC) with front panel control of
the ALC threshold, forward and reflective RF sample ports for precise power
measurements and RF output level protec-
tion. Protection is provided by DC current level sensing of all output stages.

The export classification for this equipment is
EAR99.
