THE SINGLE BEST STRATEGY TO USE FOR LOW-NOISE AMPLIFIER

PIN diodes could possibly be used, for instance, given that the bridge and shunt resistors inside a bridged-T attenuator. A further popular strategy is to implement PIN diodes as terminations linked to the 0 diploma and -90 diploma ports of the quadrature hybrid. The signal being attenuated is placed on the input port, and the attenuated result is
