Abstract:
1. A network for applying a source of a radio frequency (RF) signal to a signal processing stage forming a load with respect to said network, comprising: a first inductor coupled to said load; a transmission line connector responsive to said RF signal and coupled to said first inductor for compensating against an impedance mismatch between said connector and a transmission line, when said transmission line is coupled to said connector, and for coupling said RF signal to said load, during normal operation, said connector being susceptible to couple a surge voltage to said first inductor, when said surge voltage occurs; a surge suppressing threshold device; a second inductor coupled via said first inductor to said connector for coupling said surge suppressing threshold device to said connector to suppress said surge voltage, when said surge voltage causes said surge suppressing threshold device to turn on, said second inductor being capable of enhancing isolation of a capacitance, formed between a pair of terminals of said surge suppressing threshold device, from a signal path formed between said connector and said load at each frequency of said RF signal that is within at least 75% of a range of frequencies between 10 and 1600 MHz; and a capacitor coupled in series with said capacitance that is formed between said pair of terminals and coupled to said second inductor to form a parallel resonant circuit.
