Description: BROADBAND POWER AMPLIFIER
Information:

The ENI Model 3100LA is an all solid state Amplifier which has a flat frequency response from 2 50kHz to 150MKz. it provides up to 100W of linear power with low harmonic and intermodulation distortion. Gain is 55dB nominal, with variation of less than +_1.5dB over the entire frequency range. Input and output impedance are SOohms and the unit may be driven to full power output by most RF synthesizers, signal generators and swept^signal sources. The ENI Model 3100LA 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 3100LA is packaged for bench mounting and is shipped with rack mounting adapters. Its integral Power Supply and cooling operate from a 100/ 107.5/ 1150/ 120 or 200/ 125/ 230/ 240VAC 50/60HZ main supply. The Model 3100LA 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.
