Patent ID: 7280602

Claim:
A signal edge detector circuit having an output terminal and an input terminal for receiving microwave signals at a predetermined clock signal rate, said signal edge detector circuit comprising: an input transmission line connected to said input and output terminals to provide a path for a signal transition from said input terminal to said output terminal, said input transmission line including a node between said input and output terminals; a first reflection transmission line having first and second ends, said first reflection transmission line connected at a first end to said node providing a reflection of said signal transition, said reflection of a polarity to terminate said signal transition at said output terminal; at least one second reflection transmission line having first and second ends, said at least one second reflection transmission line connected at a first end to said node providing a reflection of said signal transition, said reflection of a polarity to cancel out said reflection from said first reflection transmission line at said node; whereby a pulse is generated at said output terminal for each leading signal edge of said microwave signals at said input terminal.
