LOW-NOISE AMPLIFIER NO FURTHER A MYSTERY

PIN diodes may very well be used, one example is, since the bridge and shunt resistors in a bridged-T attenuator. Yet another typical method is to work with PIN diodes as terminations connected to the 0 degree and -90 diploma ports of a quadrature hybrid. The sign being attenuated is placed on the input port, plus the attenuated result is taken fro
