  • Radio frequency protection circuit
    Patent number: 3992669
    Abstract: A diode switch device coupled between two circulators provides signal continuity around an active radio frequency circuit during a failure mode caused by a loss of local supply voltage. Under a normal nonfailed condition, the diode switch short circuits the bypass path, thereby preventing the input signal from bypassing the protected circuit. In the protected failure mode, the short circuit is removed and the input signal is conducted around the failed active circuit.
