THE SMART TRICK OF LOW-NOISE AMPLIFIER THAT NOBODY IS DISCUSSING

PIN diodes may very well be used, as an example, as the bridge and shunt resistors in a very bridged-T attenuator. Another typical solution is to make use of PIN diodes as terminations connected to the 0 degree and -90 degree ports of a quadrature hybrid. The sign to get attenuated is applied to the enter port, as well as attenuated result's taken
