Quadrature hybrid

The quadrature hybrid configuration can control twice the power of the simple series or shunt diode attenuators because the incident power is divided into paths by the hybrid. Reference [1] shows that the maximum power dissipated in each diode is only 25 % of the total incident power and this occurs at the 6 dB value of attenuation.
