RF Power Amplifier
The ENI / E&I 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 Ω 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 Ω load impedance, however, any
load impedance between 2 Ω and 800 Ω 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 ENI / E&I 1140L (forward power) and the power absorbed by the load (load power).
