1140L ENI RF Amplifier

Used
The 1140L is a 250 kHz 1100 Watt RF Amplifier from ENI. Amplify RF and Microwave signals to measure, test, and design circuits. Applications include radio communications, cellphones, EMI testing, and much more.

Additional Features:

  • Frequency range 9 kHz to 250 kHz, up to 450 kHz at reduced gain
  • 1400 W output power (9 kHz to 50 kHz), 1100 W (50 kHz to 250 kHz)
  • 50 dB gain (nominal)
  • Front panel metering
  • 50 Ohm impedance
  • N(f) connectors, input/output
  • 115 VAC, ± 6%; 50 to 60 Hz operation

The 1140L is an all solid state power amplifier operating over the range of 9 kHz to 250 kHz with a flat gain of 50 dB. Its 50 ohm input is compatible with any laboratory signal generator, function generator, or integrated circuit oscillator. Any load impedance (from an open to a short circuit) may be connected to the output of the 1140L without fear of damage or oscillation. The 1140L delivers maximum power transfer to a 50 ohm load impedance, however, any load impedance between 2 and 800 ohms can be driven by connecting a matching transformer between the output and the load. A built-in true average power meter measures both the power leaving the 1140L (forward power) and the power absorbed by the load (load power).
