  • Page 2: Chapter 1 Introduction

    Chapter 1 Introduction Introduction The E&I Model 411LA is an all solid state amplifier which has a flat frequency response from 150 kHz to 300 MHz. It provides up to 10W of linear power with low harmonic and intermodulation distortion. Gain is 40 dB nominal, with variation of less than +/-2.5 dB over the entire frequency range.

  • Page 3: Chapter 2 Operation

    Chapter 2 Operation 2.1 Introduction The E&I 411LA RF amplifier is used to increase the RF output level of signal sources in the 0.15 to 300 MHz range. No tuning or any other form of adjustment is required. Mains Voltage Setting The unit automatically adjusts to accommodate the available AC line voltage.

  • Page 4: Chapter 3 Technical Description

    Chapter 3 Technical Description 3.1 GENERAL DESCRIPTION The E&I Model 411LA is a linear Class A amplifier capable of increasing the output of any signal generator, frequency synthesizer, sweep generator or laboratory signal source from 150 kHz to 300 MHz. The Model 411LA is completely protected against damage due to load mismatch provided that the input RF level does not exceed 1 VRMS or 1.4V peak.
  • Page 5 RF voltmeter. Precautions The input and output of the Model 411LA should not be connected together. This will cause oscillation and may damage the input preamplifier. When the input signal voltage of the signal source is unknown, insert an attenuator between it and the Model 411LA input.
  • Page 6 (vi) Adjust the input CW signal to any frequency between 1 and 300MHz for 10W output. If you can not attain RF power, verify that: The mains fuse is correctly selected and not blown The switch is illuminated. If the mains fuse is not blown but you are still unable to get any RF power, either return the unit to E&I for repair or proceed to chapter 4.
