Информация:
                                    The ENI Model 325LA is an all solid state amplifier which
has a flat frequency response from 250 kHz to 150 MHz. It
provides up to 25W of linear power with low harmonic and
intermodulation distortion. Gain is 50 dB nominal, with
variation of less than +1.5 dB over the entire frequency
range. Input and output impedance are 50Ω and the unit may
be driven to full power output by most RF synthesizers,
signal generators and swept signal sources.
The ENI Model 325LA will deliver its rated power output into
any load impedance, regardless of match. Built-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 325LA is packaged for bench mounting and is shipping
with rack mounting adapters. Its integral power supply and
cooling operate from a 115 or 230 VAC 50/60 Hz main supply.
The Model 325LA will raise the power level of signal sources
and generators without requiring tuning or bandswitching.
The Class A linear circuitry will amplify signals of AM, FM,
SSB, TV and complex modulations limited only by their peak
input and bandwidth, with minimum distortion.
