Description: BROADBAND POWER AMPLIFIER
Information:
                                    The ENi Model 350L is an all solid state Amplifier which has
a flat frequency response from 250 kHz to 105 MHz.
It provides 50 watts of linear power with low harmonic and
intermodulation distortion. Gain is 50 dB nominal, with a
variation of less than +1.5 dB over the entire frequency
range. Input and output impedance are 50 ohms and the unit
may be driven to full power output by most RF synthesizers,
signal generators and swept signal sources.
The ENI Model 350L will deliver its rated power output into
any load impedance, regardless of match, Buiit-in protection
circuitry will absorb the power reflected from a mismatched
load without causing failure or oscillation.
Output RF voltage is displayed on the front panel meter. The
Model 350L is packaged for bench mounting and is shipped
with rack mounting adapters. Its integral power
supply and cooling operate from a 115 or 230 VAC 50/60Hz
main supply.
The Model 350L will raise the power level of signal sources
and generators without requiring tuning or band- switching.
The Class A linear circuitry will amplify signals of AM, FM,
SSß, TV and complex modulations limited only by their peak
input and bandwidth with minimum distortion.
