AH31
High Dynamic Range IF Amplifier
The Communications Edge TM
Product Information
Broader Bandwidth Reference Designs
The AH31 can be designed to achieve good performance over a broader frequency range (around one octave) by using an
additional L-C matching network at the input. An equalization R-C network can also be added at the output to slightly flatten
out the typical downward slope of the amplifier circuit.
