Broadband matching network

Image Number 3 for United States Patent #5471492.

A broadband matching network closely matches the output impedance of a broadband amplifier to the input impedance of a laser over a broad frequency band to facilitate efficient transfer of power therebetween. As a result, the broadband amplifier does not have to generate high output power levels that cause intermodulation distortion. The matching network includes a pair of matching transformers having toroidal cores and a filter circuit.
