Video switch circuit is as shown. 2N4391 FET provides the circuit with only 30Ω induction -resistance and less than 0.2pF pinch-off is capacitance. This performance can be comparable with that of the ideal high-frequency switch. The attenuation for 100MHz circuit is more than 80dB and the insertion loss is about 6dB.
