NOTES: Please contact factory for outline.
Harmonic output -10 dBc max. typical.
Input/output VSWR 2:1 typical.
Higher gain options available.
Octave and multioctave limiting amplifiers are widely
used in instantaneous frequency measurement
receivers. Three of the most important performance
requirements of limiting amplifiers are:
To minimize output power variations and provide
a constant output over a wide input dynamic
range.
To minimize the harmonic output power under
limiting conditions.
High fidelity to pulsed input signals by minimizing
overshoot and recovery times.
