PIN diodes may be utilised, one example is, since the bridge and shunt resistors inside a bridged-T attenuator. One more typical technique is to make use of PIN diodes as terminations linked to the 0 diploma and -90 degree ports of the quadrature hybrid. The signal for being attenuated is https://pin-diode-switch14791.tkzblog.com/34048947/the-smart-trick-of-coaxial-switch-that-nobody-is-discussing
