A REVIEW OF LOW-NOISE AMPLIFIER

PIN diodes may very well be used, one example is, given that the bridge and shunt resistors inside a bridged-T attenuator. A further common approach is to employ PIN diodes as terminations linked to the 0 degree and -90 degree ports of the quadrature hybrid. The sign to become attenuated is applied to the input port, plus the attenuated result's ta
