1.0 Introduction
The ETS-Lindgren Model 8000-075 RF Power Amplifier is capable of supplying a
minimum of 450 watts into a 50 ohm load over the frequency range 1000 MHz to
3200 MHz. The amplifier is designed with sufficient gain so that it may be used with
normal output levels of signal sources.
A safety interlock on the rear panel is also provided, which will mute the
amplifier when grounded.
The unit is powered by a switched mode power supply for high efficiency,
high power factor, and a wide voltage range operation. The unit is air cooled
with integral fans and is protected against faulty cooling by excess
temperature sensing.
A front panel fault indicator is provided to indicate over-temperature.
The amplifier is designed for rugged operation into a variety of loads and is primarily
intended for use as an RF power source for EMC susceptibility testing, but is also
applicable to other systems requiring a wide-band linear amplifier.
This amplifier is designated as Professional Equipment and should not be operated
by untrained staff. As this product has the capability to generate high levels of RF
energy it is not intended for use in a residential environment.
Standard Configuration
The 8000-075 amplifier system comes already assembled and connected
into a 19-inch 20U rack.
The N type input and 7/16 output connectors are located on the rear panel.
