Abstract:
1. A limiter-circuit comprising: a transmission line of quarter-wave length which has a predetermined characteristic impedance, said transmission line comprising a signal line conductor and a common line conductor; signal line input terminal connected to said signal line conductor; signal line output terminal connected to said signal line conductor; common line input terminal connected to said common line conductor; common line output terminal connected to said common line conductor; a terminator connected between said signal line input terminal and said common line input terminal; a first limiter element connected in series with said terminator and between said terminator and said common line input terminal; a first DC return element connected in parallel with the first limiter element and between said common line input terminal and a portion between the first limiter element and the terminator; a second limiter element connected between said signal line output terminal and said common line output terminal; and a second DC return element connected to in parallel with the second limiter element.
